Prepare a simple tuna salad by draining the liquid from two 5-ounce cans of water-packed tuna. Mix in 2 tablespoons of mayonnaise, 1 tablespoon of lemon juice and a chopped onion. Add a sprinkle of salt and a few shakes of black pepper to taste.
Prepare a lighter alternative to the usual mayonnaise-based tuna salad by adding 1 tablespoon of fresh chopped basil, a minced half-stalk of celery and 2 tablespoons of lemon juice to a drained 5-ounce can of water-packed tuna. Mix the ingredients, and add extra virgin olive oil, salt and pepper to taste. If you desire, add a finely chopped scallion.
Another simple but flavorful variation on tuna salad can be made by adding some traditional Thai flavors. Combine three cans of drained water-packed tuna with a chopped red bell pepper, half of a diced red onion, 3/4 cup of sesame oil and one thinly sliced cucumber. Once all of the ingredients are mixed, stir in the juice of one lime. Lastly, add salt and pepper to taste. You can top this dish with sesame seeds or fresh basil.
All of these recipes can be served on sandwich bread or on lettuce for a meal low in carbohydrates.
