1 1/2 lb. ground beef
1/2 c. chopped onion
1/4 c. chopped green pepper
4 oz. can mushroom pieces and stems, drained
1/2 tsp. salt
1/4 tsp. pepper
1/4 tsp. oregano leaves
2 (7.5 oz.) cans buttermilk or country biscuits
8 oz. Mozzarella cheese slices

Heat oven to 375 degrees. Grease cookie sheet. In large skillet, brown ground beef, onion, and green pepper; drain. Stir in tomato sauce, mushrooms and seasonings; mix well. Simmer while preparing dough.

Separate each can dough into 10 biscuits. On prepared cookie sheet, arrange biscuits in 5 rows of 4 biscuits each, overlapping edges; press dough to form 14x10 inch rectangle, forming scalloped edge around outside.

Spread meat mixture evenly over biscuits to within 1 inch of edges. Place cheese over meat mixture. Bake at 375 degrees for 15-20 minutes or until edges are golden brown.
