Stir in a can of Tuna. (Note, a former 6.5 ounce can of tuna is now down to 4 ounces of tuna with an ounce of water for ballast.)
Kraft Mac n Cheese Tuna Casserole ( adopted from the Original Creamettes Mac n Cheese)
Kraft Mac n Cheese, cook following directions on box. When Mac is ready Add one can cream of mushroom soup, ad half soup can of milk, add two cans tuna with water drained, ad bit of minced garlic, 1/4 cup finely chopped onion. Mix all together in a casserole dish and top with crushed saltine crackers or crushed potato chips. Bake in 350 oven for 1/2 hour. After cooking I add my own canned peas to my serving, wife likes frozen peas. You can also use a part of a bag of mixed veggies (peas,carrots,green beans) to the casserole and cook with the casserole.
