How to Make Tuna Salad Sandwich with Avocado
Prepare the Tuna Salad
- In a mixing bowl, combine two cans of drained solid white albacore tuna in water, finely chopped celery, chopped Kalamata olives, finely chopped red onion, and drained capers.
- Add the zest and juice of one lemon to the mixture.
- Drizzle a quarter cup of extra-virgin olive oil over the ingredients.
- Mix everything well until it's well-combined.
- Season with salt and pepper to taste. For the best flavor, let it sit in the fridge for at least an hour to allow the flavors to meld.
Toast the Bread
- If you prefer toasted bread, toast eight slices of whole-grain bread until they're golden brown. This step is optional but highly recommended for added texture.
Assemble the Sandwich
- Lay out four slices of the toasted bread on your work surface.
- Spread a generous portion of the prepared tuna salad onto each slice.
- Add slices of ripe avocado on top of the tuna salad.
- If you're using provolone cheese, add a slice on top of the avocado for each sandwich.
- Place a handful of fresh arugula on top.
- Complete the sandwich by placing the remaining slices of toasted bread on top.
Tips and Tricks for the Perfect Tuna Salad Sandwich with Avocado
Choose Quality Tuna: Opt for solid white albacore tuna in water for a meaty texture and clean flavor. The quality of the tuna will significantly impact the overall taste of your sandwich.
Let Flavors Marinate: Although you can eat the tuna salad immediately, letting it sit in the fridge for an hour or more allows the flavors to meld, resulting in a more flavorful and cohesive dish.
Avocado Ripeness Matters: Make sure your avocados are perfectly ripe for the creamiest texture and best flavor. A ripe avocado should give slightly when pressed but not feel mushy.
Bread Selection: While the recipe calls for whole-grain bread, feel free to switch it up based on your preferences. Sourdough, rye, or even a hearty ciabatta could add a different, delightful twist to the sandwich.
Make It Your Own: Feel free to customize the sandwich to your taste. Want a bit of heat? Add some sliced jalapeños. Prefer a different kind of cheese? Swap out the provolone for cheddar or Swiss. The beauty of this recipe is its flexibility.
Sides for Tuna Salad Sandwich with Avocado
Elevate your lunch or dinner experience by pairing this scrumptious Tuna Salad Sandwich with Avocado with some delightful sides. Here are some options that complement the flavors and textures of the main course:
- Simple Green Salad: A fresh green salad with a light vinaigrette can offer a refreshing counterpoint to the rich and savory flavors of the sandwich. Use mixed greens, cherry tomatoes, and cucumber for a simple yet effective side.
- Sweet Potato Fries: The sweetness of baked or air-fried sweet potato fries pairs beautifully with the tangy and salty elements of the tuna salad. Plus, they add a satisfying crunch.
- Coleslaw: A tangy coleslaw can bring an additional layer of crunch and freshness. Opt for a vinegar-based dressing rather than a creamy one to keep the meal from becoming too rich.
- Pickle Spears: The acidity and crunch of pickles cut through the richness of the tuna and avocado, making them a classic and effective side option.
- Fresh Fruit: If you're looking for something light, a bowl of mixed fresh fruit like pineapple, strawberries, and blueberries can offer a refreshing and slightly sweet balance to the meal.

Tuna Salad Sandwich with Avocado - FAQ
Absolutely! Making the tuna salad a day in advance allows the flavors to meld together, resulting in an even more delicious sandwich. Just store it in an airtight container in the fridge until you're ready to assemble your sandwiches.
Yes, you can use tuna in oil, but it will add more calories and potentially alter the flavor profile of the salad. If you choose to use tuna in oil, you might want to reduce the amount of olive oil in the recipe.
If Kalamata olives aren't to your taste or you don't have them on hand, you can use green olives, black olives, or even sun-dried tomatoes for a different twist.
While this recipe is designed around tuna, you're welcome to add other proteins to suit your preference. Crispy bacon could add a salty crunch, and grilled chicken could make the sandwich even heartier. Just remember that additional proteins will change the nutritional profile of the sandwich.
