I think this recipe originally came off a box of American pasta. It's one my mom used to make and it's one that I still make today. My family loves it.
1 box large pasta shells
1 lb ground beef
1 lb bulk sausage
1 cup flavored dry bread crumbs
1 cup shredded mozzarella cheese
3/4 cup finely chopped onion
3/4 t. oregano
1/2 t. salt
1/2 t. pepper
3 cups (about a 28 oz jar) Pasta sauce (or a double batch of homemade Marinara sauce)
grated Parmesan cheese
Cook pasta, drain. Cook sausage and beef together until no longer pink. Drain. Mix with eggs, bread crumbs, cheese, onion, and spices. Pour some sauce into the bottom of a 9 x 13 pan. Fill each shell with the meat mixture. Put the filled shells in the pan. Cover with the rest of the pasta sauce. Sprinkle with Parmesan and bake at 375 for about 35-40 minutes or until hot and bubbly.
These freeze well. (Thaw them and then add the sauce and bake as directed.) Serve with salad and garlic bread.
