A recipe for tuna salad sandwiches calls for 12 ounces of high-quality tuna, two stalks of celery cut in half lengthwise and thinly sliced, and 3 tablespoons of light mayonnaise. Another ingredient is an apple that you have peeled, cored and diced into 1/4-inch pieces.
The rest of the ingredients are 2 tablespoons of chopped fresh basil leaves, 1 tablespoon of fresh squeezed lemon juice, eight slices of sourdough bread, and coarse salt and freshly ground black pepper.
Combine all the ingredients except for the bread into a medium bowl and mix well. Spread the salad on four slices of bread, and top each sandwich with the remaining slices.
Another tuna salad sandwich recipe has the following ingredients: two 6-ounce cans of unsalted white tuna, 1/2 cup of diced celery, 1/3 cup of fat-free mayonnaise, 1 teaspoon of lemon juice and four lettuce leaves. This recipe calls for eight slices of whole wheat bread.
Place the tuna in a bowl and flake it with a fork. Add the celery, lemon juice and mayonnaise, and blend the ingredients together.
Place one lettuce leaf on a slice of bread. Top with one-quarter of the tuna salad, and top this with another slice of bread. Repeat until all the sandwiches are made, and serve them at once.
