Why You’ll Love This Recipe

• High-protein, high-satiety: Tuna and rice deliver long-lasting energy without the heavy, nap-inducing slump.
• Ridiculously fast: With pantry tuna and microwave rice, you’re 10–12 minutes from done.
• Light but craveable: Sesame, soy, and rice vinegar bring big flavor with minimal effort.
• Meal-prep friendly: Scales up easily and holds well for a few days with smart storage.
• Budget-conscious: Uses humble ingredients to create a restaurant-level bowl. Your wallet says thanks.

Ingredients

• 1 1/2 cups cooked rice (jasmine, sushi, or brown; day-old works great)
• 1 (5–6 oz) can tuna in water or olive oil, drained
• 1 small cucumber, thinly sliced (Persian or English for fewer seeds)
• 2 green onions, thinly sliced
• 1 small carrot, julienned or shredded (optional but adds crunch)
• 1/2 ripe avocado, sliced or cubed
• 2 tablespoons edamame, thawed (optional)
• 1 tablespoon toasted sesame seeds (mix of white and black if you have)
• 1 sheet nori, snipped into thin strips (optional but excellent)

For the sesame-soy dressing:

• 1 1/2 tablespoons low-sodium soy sauce or tamari
• 1 tablespoon rice vinegar
• 1 teaspoon toasted sesame oil
• 1 teaspoon honey or maple syrup
• 1 teaspoon sriracha or chili crisp (optional heat)
• 1 teaspoon grated fresh ginger (or 1/4 teaspoon ground ginger in a pinch)
• 1 small garlic clove, finely grated
• Pinch of sea salt and freshly cracked black pepper, to taste

Instructions

1. Prep the rice: If using cold rice, microwave with a splash of water for 45–60 seconds to fluff.

   For sushi vibes, sprinkle 1 teaspoon rice vinegar over warm rice and gently fold.

2. Mix the dressing: In a small bowl, whisk soy sauce, rice vinegar, sesame oil, honey, sriracha, ginger, and garlic. Taste and adjust—more vinegar for brightness, more honey for balance.
3. Dress the tuna: Add half of the dressing to the drained tuna and stir gently to coat. You want it glossy, not mushy.
4. Slice the crunch: Thinly slice cucumber and green onion.

   Julienne carrot if using. Keep textures varied for a better bite.

5. Assemble the bowl: Add rice to a bowl. Top with dressed tuna, cucumber, carrot, avocado, edamame, and green onion.
6. Finish strong: Drizzle remaining dressing over everything.

   Add sesame seeds and nori strips. A squeeze of lime? Not traditional, but excellent.

7. Serve immediately: Mix at the table so the cucumber stays crisp and the rice stays fluffy.

Preservation Guide

• Fridge: Store components separately for best texture.

  Dressed tuna: up to 3 days. Cooked rice: 3–4 days. Veggies: 2–3 days.

  Avocado should be sliced fresh.

• Meal prep tip: Portion rice and tuna in containers. Pack cucumbers and carrots in a small side cup. Add dressing right before eating.
• Freezer: Freeze rice in single portions for up to 1 month.

  Do not freeze tuna once mixed with dressing; the texture suffers.

• Food safety: Keep tuna chilled below 40°F (4°C). If it smells off, it is off—don’t negotiate.

What’s Great About This

• Macro-balanced: Protein from tuna, complex carbs from rice, healthy fats from sesame and avocado. Your body is clapping.
• Low effort, high payoff: Minimal chopping, one bowl, massive flavor.
• Customizable: Works with pantry swaps—brown rice, quinoa, or cauliflower rice if you’re going lighter.
• Weeknight hero: When you’re tired but still want something that feels like you tried.

Pitfalls to Watch Out For

• Overdressing the tuna: It can get soggy and salty fast.

  Start with less, add more as needed.

• Warm cucumbers: Add cold veg right before serving to keep the crunch. Warm cukes are a vibe… just not a good one.
• Rice clumps: Cold rice needs a splash of water and a quick reheat to loosen. Don’t fight the brick—fix it.
• Salt overload: Soy sauce + canned tuna can be sodium-heavy.

  Use low-sodium soy and taste as you go.

Recipe Variations

• Spicy Kewpie Mash-up: Stir 1 tablespoon Kewpie mayo with 1–2 teaspoons sriracha and a squeeze of lime; fold into the tuna for a spicy-creamy vibe.
• Poke-Inspired: Swap canned tuna for high-quality sushi-grade tuna cubes. Marinate briefly in the dressing plus a touch of sesame oil and scallions.
• Mediterranean Detour: Use lemon juice, olive oil, dill, and capers; swap cucumber for cherry tomatoes and add olives. Rice or farro both work.
• Grain Swap: Use brown rice, quinoa, or cauliflower rice for different macros.

  FYI, quinoa adds a nutty pop.

• Veg-Forward: Add shredded cabbage, radishes, or pickled onions for extra crunch and acidity.
• Sweet Heat: Drizzle with chili crisp and a touch of honey. The contrast slaps.
• Egg Upgrade: Top with a jammy 7-minute egg or a crispy fried egg for extra protein and richness.

FAQ

Can I use brown rice instead of white?

Yes. Brown rice adds a hearty chew and extra fiber.

Just make sure it’s cooked tender and fluffed, since dense rice can make the bowl feel heavy.

What type of tuna is best?

Albacore is meaty and mild; skipjack has a stronger flavor and is usually more budget-friendly. Tuna packed in olive oil brings richness, but drain it lightly so the dressing still shines.

Is this good for meal prep?

Absolutely. Keep rice, tuna, and veggies separate and assemble just before eating.

Add dressing last to keep everything perky and fresh.

How do I make it gluten-free?

Use tamari or coconut aminos instead of soy sauce. Everything else here is naturally gluten-free, assuming your sesame seeds and condiments aren’t cross-contaminated.

What if I don’t like raw cucumber?

Swap in lightly pickled cucumber (salt + rice vinegar, 10 minutes) or use shredded cabbage for crunch. Even steamed green beans work in a pinch.

Can I make it without sesame?

Yes.

Use olive oil instead of sesame oil, skip the seeds, and brighten with extra lime and herbs like cilantro. Different, but still great.

How spicy is it?

Mild by default. Add sriracha or chili crisp to your liking.

If you’re spice-averse, leave it out and add a tiny pinch of white pepper for warmth.

Is canned salmon a good substitute?

Totally. Canned salmon adds healthy fats and a richer flavor. Remove any skin/bones if that’s not your thing, and proceed with the same dressing.

Can I serve it cold?

Yes, it’s great cold.

Just keep the rice chilled and fluff it with a fork before assembling so it doesn’t clump. Cold bowls hit different on hot days, IMO.

How can I boost protein further?

Double the tuna, add edamame, or top with a jammy egg. You can also mix in Greek yogurt with the dressing for extra protein and creaminess.
