Preheat the oven to 400 F.
In a large skillet, brown the ground beef with the minced onion and garlic powder. Once browned, drain and then stir in the marinara sauce and tomato paste, and let simmer for 5 to 10 minutes.
In a large mixing bowl, combine the ricotta cheese, egg and Parmesan cheese with half of the shredded mozzarella cheese.
To the baking dish, layer the lasagna noodles, ground beef and tomato mixture, and ricotta cheese mixture. Make 2 layers, then top with lasagna noodles and the remaining shredded mozzarella cheese.
Bake in the preheated oven for 25 to 30 minutes, or until sauce is bubbling around the sides of the dish.
Prepare the salad.
Serve 10-Minute Lasagna with salad.
