1 lb. bulk pork sausage
½ C. onion, finely chopped
1 tsp. salt
4 slices fresh bread, made into crumbs
1 egg beaten

¼ C. fresh parsley, chopped or 1 ½ tsp. dried    flakes
20 jumbo pasta shells, parboiled and drained
two 19 ½-oz. cans spaghetti sauce
   (I use one large jar of Ragu or Prego)
8 oz. grated Mozzarella cheese

Fry the sausage until brown and crumbly.  Drain well.  Add salt, breadcrumbs, egg, and parsley.  Mix thoroughly.  Using a teaspoon, fill shells with the sausage mixture.

Pour ¼ of the spaghetti sauce into a 9x13 baking dish.  Arrange shells in the dish and pour remaining sauce over shells.  Sprinkle with cheese.  Cover with foil and bake in a pre-heated oven at 350° for 30 minutes.  Remove the foil and bake 10 minutes longer.
