For a little added protein add a can or two of drained tuna or chicken. Voila! Quick and easy mac & cheese without all the sodium and food coloring of that boxed stuff. Need an even quicker variety? Cook up your macaroni, drain and return to pot. Add about 1/4 c milk and 5 or 6 slices of American cheese (or to taste). Stir together and serve. If your cheese is too thick, add a little more milk. If it's too runny, add a little more cheese.
