3/4 lb. beef
4 tbsp. minced onion
1 tsp. salt
1/4 tsp. pepper
1 lb. Ricotta cheese
2 c. grated Mozzarella
1 egg, beaten
1 tsp. parsley
1 pkg. pasta shells
2 pt. favorite sauce (I prefer Ragu)

Cook beef, onion, salt, and pepper. Drain and cool. Combine ricotta, Mozzarella, egg, parsley and cooled beef. Prepare shells as package directs. Drain.

Fill shells with 1/4 cup filling. Pour 1/3 sauce into 9"x13" baking dish, just enough to cover bottom of dish. Place shells, crease side down, in dish. Pour remaining sauce over top and sprinkle with mozzarella. Bake, covered at 350 degrees for 30 minutes.
