For this sandwich you will need one can of tuna or chicken, 1 serving (30g) light mayo, celery if desired, seasoning of choice, low-fat or fat free shredded cheddar cheese, and bread if desired. Try to watch for overly salty seasonings as the canned tuna or chicken may already have higher sodium content (especially the chicken). If your canned chicken is high in sodium, you can add a little water into the can after draining the original liquid, and re-drain to remove additional salt content.
Mix tuna with light mayo, seasoning, and chopped celery in a bowl. Spread evenly over bread and top with shredded cheddar. Toast your sandwich (open-face) until cheddar is melted. Serve with some cauliflower chips or pickles - Enjoy! (40g of protein, 400 calories est.)
