Pizza Burgers

Serves 6

1 pound extra-lean ground beef (I think I would have liked bigger burgers so maybe 1-1/2 pounds of ground beef would be better)
1 tsp salt
1 tsp pepper
1 tsp oregano
1/2 cup tomato sauce
1/2 cup muchrooms, thinly sliced
1 tbsp butter
4 oz (1 cup) fat free mozzarella cheese, grated
1 tbsp parsley
6 hamburger buns

In skillet over medium-high heat, saute mushroom slices in butter. Remove from heat. In large bowl combine beef, salt, pepper and oregano. Form beef mixutre into six equal patties. Cook patties in non-stick skillet for 3 minutes (or until cooked through). Spread each patty with 1 tbsp tomato sauce and 1 tbsp mushrooms. Divide cheese evenly between patties. Serve sprinkled with parsley in hamburger buns.
