What You’ll Need

• 2 cans (5–6 oz each) tuna, drained (water-packed or olive oil-packed)
• 1 can (15 oz) white beans (cannellini or great northern), drained and rinsed
• 1 small red onion, finely diced (or 2–3 scallions, sliced)
• 1 cup cherry tomatoes, halved (optional but great for color)
• 1 small cucumber, chopped
• 1/4 cup fresh parsley, chopped (or basil, dill, or a mix)
• 2 tablespoons capers, drained (optional, for briny bite)
• 1/4 cup extra-virgin olive oil
• 1 large lemon, zested and juiced (about 3–4 tablespoons juice)
• 1 teaspoon Dijon mustard
• 1 small garlic clove, finely grated or minced
• 1/2 teaspoon honey or maple syrup (optional, to balance acidity)
• Salt and freshly ground black pepper, to taste
• Red pepper flakes (optional, for heat)

Step-by-Step Instructions

1. Prep the produce. Finely dice the red onion, chop the cucumber, halve the cherry tomatoes, and chop the parsley.

   Grate or mince the garlic. Zest and juice the lemon.

2. Make the lemon dressing. In a small bowl, whisk together the lemon zest, lemon juice, Dijon mustard, garlic, olive oil, and honey. Season with a generous pinch of salt and several grinds of black pepper.

   Taste and adjust—add more lemon for brightness, more oil for richness, or a pinch of honey if it’s too sharp.

3. Combine tuna and beans. In a large bowl, add the drained tuna and white beans. Use a fork to break up the tuna into bite-size pieces, keeping some texture. Don’t mash the beans; keep them intact for a creamy bite.
4. Add veggies and herbs. Fold in the onion, cucumber, tomatoes, parsley, and capers.

   This adds crunch, color, and freshness.

5. Dress the salad. Pour the lemon dressing over the mixture. Toss gently until everything is well coated. Taste and adjust seasoning—add more salt, pepper, or a pinch of red pepper flakes if you like heat.
6. Let it rest (if you can). For the best flavor, let the salad sit for 10–15 minutes so the beans soak up the dressing.

   If you’re in a hurry, it’s still great right away.

7. Serve your way. Enjoy it as-is, spooned over greens, tucked into pita, piled on toast, or served with crackers. A squeeze of extra lemon and a drizzle of olive oil at the table makes it shine.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors deepen over time, but the veggies may soften slightly.

If you plan to keep it longer than a day, you can store the dressing separately and add it just before serving to preserve crunch.

If the salad tastes muted after chilling, brighten it with a splash of lemon juice, a pinch of salt, and a drizzle of olive oil before serving. Do not freeze; the texture of the beans and vegetables won’t hold up well.

Health Benefits

• High in protein: Tuna offers lean protein that helps keep you full and supports muscle maintenance.
• Fiber-rich: White beans add fiber for digestion, heart health, and steady energy.
• Healthy fats: Extra-virgin olive oil provides monounsaturated fats and antioxidants.
• Low in refined carbs: This salad is naturally low in refined carbohydrates and works well for balanced eating plans.
• Micronutrients galore: Lemon, herbs, tomatoes, and onion contribute vitamin C, potassium, and phytonutrients.

What Not to Do

• Don’t skip rinsing the beans. Rinsing removes excess sodium and the starchy liquid, which can make the salad gummy.
• Don’t overmix. Stir gently to keep the beans intact and the tuna pleasantly chunky, not mushy.
• Don’t under-season. Beans soak up flavor. Taste as you go and adjust salt, pepper, and lemon.
• Don’t drown it in dressing. Start with most of the dressing and add more as needed.

  You want glossy, not soupy.

• Don’t use old tuna. Freshness matters. Good-quality canned tuna makes a big difference in flavor.

Alternatives

• Protein swaps: Use canned salmon, sardines, or shredded rotisserie chicken. For vegetarian, try marinated chickpeas or extra beans.
• Bean options: Cannellini are classic, but great northern, navy, or butter beans work well.
• Herb variations: Dill adds a deli-style note, basil brings sweetness, and cilantro gives a fresh twist.
• Add-ons: Olives, roasted red peppers, artichoke hearts, sun-dried tomatoes, or chopped celery for extra crunch.
• Greens and grains: Serve over arugula or spinach, or bulk it up with cooked farro, quinoa, or couscous.
• Dairy boosts: Add crumbled feta, shaved Parmesan, or fresh mozzarella pearls for creaminess.
• Vegan dressing: Skip honey and use maple syrup or a pinch of sugar; omit tuna and double the beans.

FAQ

Can I use tuna in olive oil instead of water-packed?

Yes.

Tuna packed in olive oil is richer and more flavorful. If using it, reduce the olive oil in the dressing slightly, then adjust to taste so the salad isn’t overly oily.

How can I make this ahead for meal prep?

Mix the beans, tuna, and dressing up to a day in advance. Add delicate ingredients like tomatoes, cucumber, and herbs just before serving to keep them crisp.

Store in separate containers if you prefer maximum freshness.

What if I don’t like raw onion?

Soak the diced onion in cold water for 10 minutes, then drain—it mellows the bite. Or swap in scallions, chives, or a small shallot for a milder flavor.

Is there a gluten-free option?

The salad is naturally gluten-free. Just watch any add-ins like bread, crackers, or couscous.

Serve it over greens or with gluten-free crackers if needed.

How do I prevent the salad from getting watery?

Dry the beans well after rinsing, and pat the tuna if it’s very wet. Salt the veggies lightly and add dressing just before serving if you’re concerned about moisture. A quick stir before serving redistributes any liquid.

Can I use dried beans instead of canned?

Absolutely.

Cook 1 cup dried white beans until tender, then cool completely before using. Make sure they’re well-drained so the dressing clings nicely.

What can I use instead of Dijon?

Use whole-grain mustard for texture or yellow mustard in a pinch. You can also skip mustard and add a teaspoon of white wine vinegar for tang.

How can I make it spicier?

Add red pepper flakes to the dressing, toss in a chopped fresh chili, or drizzle with Calabrian chili oil.

Start small and build the heat to your liking.
