My non-ricotta cheese-eating husband always raved about "the meat stuffed shells his mom used to make." His grandmother recently wrote to the TV guide (where this recipe originated) and they were kind enough to send back the recipe, dated September 13, 1976. I have to agree, these are delicious! Serve with a tossed salad and garlic bread. The prep time includes the pasta/beef cooking; the cook time is the baking time for the casserole.
