Mix 1 can of tuna with 1⁄2 cup (0.12 L) of mayonnaise and spread it and 1⁄4 cup (0.059 L) of shredded cheese over a tortilla. Fold the tortilla in half and heat one side over a lightly greased skillet, then flip the tortilla after 3-5 minutes to cook the other side. You can use any kind of shredded cheese with this meal, but most recipes call for cheddar cheese. Cook boxed macaroni and cheese over a stove top and add the cheese sauce as directed by the box. After adding the cheese sauce, stir in a can of tuna and serve when thoroughly mixed. You can also add a can of tuna to homemade mac and cheese for a complex, cheesy meal. Mix a can of tuna salad with 1⁄2 cup (0.12 L) of mayonnaise and lemon juice to taste. Chop a cucumber and top each slice with tuna, diced tomatoes and green onions, and a sprinkle of paprika. Combine a can of tuna with a diced avocado and add a diced tomato, a chopped celery stalk, and the juice from 1/2 of a squeezed lemon. Divide the mix in half and fill either a bowl or the 2 halved avocado shells to serve.  If you're following the Paleo diet, this recipe is Paleo-friendly. You can also stuff cooked zucchini with this recipe and top with cheese for a warm, equally healthy snack. Crack 4 eggs in a pan and cook over high heat while mixing continuously. When you have scrambled the eggs, add a can of tuna, 1.75 tablespoons (25.9 mL) of olive oil, a diced onion, and oregano to taste and fry for 4-5 minutes before serving. This meal pairs especially well with fried potatoes when eaten for breakfast.
