This recipe offers a delightful twist on the classic tuna sandwich, combining fresh and crunchy ingredients for a satisfying meal.
Combine the mayonnaise, celery, walnuts, onion, sugar, salt, and lemon pepper in a mixing bowl.
Ensure all ingredients are evenly mixed for a consistent flavor.
Add the tuna, diced apple, and halved grapes to the bowl and gently fold them into the mixture.
Be gentle while mixing to keep the apple and grapes intact.
Spread the tuna mixture evenly onto three slices of bread.
Use a butter knife for easy spreading.
Top each with a lettuce leaf and another slice of bread.
Press gently to secure the sandwich layers.
Serve the sandwiches immediately or wrap them for later.
Pair with a side salad or chips for a complete meal.
