2 pieces reduced-calorie, whole-grain bread (with no more than 50 calories per slice)

6 oz canned light tuna, packed in water, drained well

2 tsp low-fat mayonnaise

2 tsp minced onion

4 tomato slices

4 onion slices

pickles (optional)

4 tbs reduced-fat shredded cheese, any variety

Preheat the broiler and lightly toast the bread.

Mash the tuna with the mayonnaise and minced onion.

Spread the tuna mixture evenly over each slice of bread and top each with 2 tomato slices, 2 onion slices, pickles, if desired, and 2 tbs cheese. Place back under the broiler until the cheese is hot and bubbly. Enjoy open-faced.
