Ingredients

• 1 1/2 pounds ground beef
• 1 small onion, chopped
• 1 (28 ounce) jar spaghetti sauce
• 3 pounds frozen cheese ravioli, thawed
• 4 cups shredded mozzarella cheese

Instructions

1. Preheat oven to 375 degrees F (190 degrees C).
2. In a skillet over medium heat, brown ground beef with onion; drain grease. Pour in spaghetti sauce and simmer 5 minutes.
3. In a 9x13 inch baking dish, spread enough sauce and beef to cover bottom and put a layer of ravioli down end to end. Spread a layer of sauce and cheese just like you would with regular lasagna. Keep layering and finish with sauce on top.
4. Bake uncovered in a preheated oven for 1 hour. Let sit for 5 minutes before serving.
