Classic Creamy Tuna Salad Sandwich

Drain the Tuna

Open all three cans of tuna and drain each one thoroughly by pressing the lid against the fish over the sink.

Flake the Tuna

Add the drained tuna to the large mixing bowl and break it apart with a fork until no large chunks remain.

Make the Dressing

Add the mayonnaise and Greek yogurt to the bowl with the tuna.

Add the Dijon mustard, lemon juice, garlic powder, salt, and black pepper to the bowl.

Stir everything together until the dressing is fully combined and creamy.

Add the Mix-Ins

Add the diced celery, red onion, and fresh dill to the tuna mixture.

Fold everything together gently until the vegetables are evenly distributed throughout.

Taste and Adjust

Taste the tuna salad and add more salt, pepper, or lemon juice to your liking.

Toast the Bread

Toast all 8 slices of whole grain bread until golden and crisp.

Assemble the Sandwiches

Lay one slice of toasted bread on a clean work surface and place a lettuce leaf on top.

Spoon one quarter of the tuna salad (about 1/2 cup) evenly over the lettuce.

Lay 2 to 3 tomato slices on top of the tuna salad.

Place the second slice of toasted bread on top and press down gently.

Cut and Serve

Cut each sandwich diagonally in half and serve immediately.
