This spaghetti pie is a sure family pleaser. The beefy spaghetti is a complete meal baked in a deep-dish pie plate or casserole. Serve the dish with a caesar salad and crusty bread. Use a jar of spaghetti sauce in this recipe or your favorite homemade sauce. To vary the flavor a bit, use part italian sausage in the filling. The corn is a tasty addition, but feel free to leave it out if you'd like. Or add some sliced ripe olives. If you want to include more vegetables, cook 1/2 cup of finely chopped celery and a shredded carrot in the skillet with the ground beef.
