What Makes This Special

This sandwich brings together simple ingredients in a way that feels fresh and satisfying. Creamy avocado and mild white beans create a rich base without any mayo.

A splash of lemon, a little Dijon, and fresh herbs dial up the flavor in seconds.

It’s also a true everyday recipe. You can make the smash ahead, build your sandwich when you’re ready, and add whatever crisp veggies you have on hand. Plus, it’s high in fiber and protein, so it actually keeps you full.

Ingredients

• 1 ripe avocado (Hass preferred)
• 1 can (15 oz) white beans (cannellini or great northern), drained and rinsed
• 2 tablespoons lemon juice (about half a lemon), plus more to taste
• 1 teaspoon lemon zest (optional but brightens the flavor)
• 1 to 1½ teaspoons Dijon mustard
• 1 small garlic clove, finely grated or minced
• 2 tablespoons red onion, finely chopped (or use shallot)
• 2 tablespoons fresh herbs (dill, parsley, or chives), chopped
• 1 to 2 tablespoons extra-virgin olive oil (optional for richness)
• Salt and black pepper, to taste
• 4–6 slices whole-grain or sourdough bread, toasted if you like
• Toppings: tomato slices, cucumber ribbons, shredded lettuce or sprouts, pickled onions, sliced radishes
• Optional extras: red pepper flakes, capers, everything bagel seasoning

Instructions

1. Prep the beans and avocado: Add the drained, rinsed white beans to a mixing bowl.

   Halve and pit the avocado, then scoop it into the bowl with the beans.

2. Season the base: Add lemon juice, lemon zest, Dijon, garlic, red onion, herbs, and a pinch of salt and pepper. If using, drizzle in the olive oil.
3. Smash to your texture: Use a fork or potato masher to mash the beans and avocado together. Leave some beans partially intact for texture.

   Taste and add more lemon, salt, or pepper as needed.

4. Toast the bread: Toast your bread slices for a sturdier sandwich and extra crunch. This also helps with any juicy toppings like tomato.
5. Assemble: Spread a generous layer of the avocado-bean smash on one slice of bread. Pile on your toppings—tomato, cucumber, and lettuce or sprouts all work well.
6. Finish and serve: Sprinkle with red pepper flakes or everything seasoning if you like.

   Top with the second slice of bread, press gently, slice in half, and serve.

How to Store

The smash keeps best in an airtight container in the fridge for up to 2 days. To slow browning, press a piece of parchment directly on the surface and squeeze in an extra teaspoon of lemon juice. Stir before using.

Assembled sandwiches are best eaten the day you make them.

If packing for later, keep the smash and bread separate and assemble right before eating. Store sliced toppings in a small container lined with a paper towel to absorb moisture.

Health Benefits

• Heart-healthy fats: Avocado provides monounsaturated fats that support healthy cholesterol levels.
• Plant protein and fiber: White beans add protein and plenty of fiber, which supports digestion and steady energy.
• Vitamins and minerals: You’ll get potassium, folate, and magnesium from the avocado and beans, plus vitamin C from lemon and veggies.
• Balanced and satisfying: The combo of healthy fats, fiber, and protein makes this sandwich filling without feeling heavy.

Pitfalls to Watch Out For

• Underripe avocado: If the avocado is too firm, the texture will be chalky and the smash won’t come together. Look for slight give when pressed.
• Over-mashing: If you puree it completely, the mix can turn gloopy.

  Leave some beans intact for a better bite.

• Under-seasoning: Beans are mild and need enough salt, lemon, and Dijon to shine. Taste as you go.
• Watery veggies: Tomatoes can make the sandwich soggy. Pat slices dry or place them above a barrier layer of greens.
• Thin bread: Flimsy bread can fall apart.

  Use sturdy whole-grain, sourdough, or toast your slices.

Variations You Can Try

• Green goddess style: Add basil, extra dill, and a handful of spinach to the smash. Blend a third of it briefly for a greener color.
• Spicy kick: Mix in chopped jalapeño, red pepper flakes, or a splash of hot sauce. Add pickled peppers for tang.
• Mediterranean twist: Fold in chopped olives, capers, and sun-dried tomatoes.

  Finish with a drizzle of olive oil and cracked pepper.

• Extra protein: Stir in hemp seeds or finely chopped toasted walnuts. Both add texture and staying power.
• Gluten-free: Use your favorite gluten-free bread or serve the smash in lettuce wraps or on rice cakes.
• Wrap or bowl: Roll it into a whole-grain tortilla with crunchy veggies, or serve the smash over greens with cucumbers and seeds.

FAQ

Can I make the smash ahead of time?

Yes. Make it up to 2 days ahead and store it airtight with parchment pressed on the surface.

Add a little extra lemon to prevent browning and stir before serving.

What kind of white beans work best?

Cannellini and great northern beans both work well because they’re creamy and mild. Navy beans are fine too, but they can be softer, so mash gently to keep some texture.

Do I need the olive oil?

No. The avocado already provides creaminess and healthy fats.

Olive oil adds richness and mouthfeel, but you can skip it to keep the sandwich lighter.

How can I make it nut-free and soy-free?

This recipe is naturally nut-free and soy-free as written. Just choose a bread that fits your needs and avoid any toppings that include nuts or soy.

What if I don’t like raw onion?

Use shallot for a milder flavor, or soak the chopped onion in cold water for 10 minutes and drain. You can also swap in thinly sliced green onions or extra herbs.

Can I freeze the avocado-bean smash?

Freezing isn’t great here.

The texture can become watery and grainy once thawed. It’s best to make smaller batches and enjoy fresh.

What’s the best bread for this sandwich?

Hearty breads like sourdough, multigrain, or a thick country loaf hold up best. Toasting helps create structure and keeps everything from getting soggy.
