I read it, tried it and liked it:
1/2 c. celery
1/2 c. chopped tomato
1/2 c. tuna
1 tbsp. lite or f/f mayo or you can use f/f or reduced fat ranch dressing
Mix ingredients together and serve on a bed of lettuce or in a pita.
It is kind of on the tuna salad side but oh well.
There's always tuna melts:
1 can tuna
1/2 can 98% fat-free cream of mushroom soup
2 tbsp. chopped onion (can sub dried onion)
Mix together and spread on a whole wheat bun halves (leave open faced on baking sheet) and bake for 7-10 minutes. Top with f/f cheese or reduced fat cheese and bake 2-3 minutes longer or until cheese melts.
