Shortcut Lasagna is a quick and easy version of the classic Italian dish. It is made with layers of lasagna noodles, ground beef or sausage, marinara sauce, and cheese. This recipe skips the traditional step of making a homemade sauce and instead uses store-bought marinara sauce for convenience. The lasagna is assembled and baked in the oven until the cheese is melted and bubbly. It's a delicious and satisfying meal that can be prepared in a fraction of the time.
