Brown the ground chuck in a large skillet.

Add the chopped onion to the skillet with the browned meat.

Cook the onion until it becomes tender.

Stir in the canned tomatoes, tomato paste, and tomato soup.

Add salt, oregano, and garlic (or garlic powder) to the sauce.

Simmer the sauce for 30 minutes, stirring occasionally.

Preheat oven to 375°F (190°C).

Cook lasagna noodles according to package directions until al dente.

In a baking dish, layer the lasagna noodles, meat sauce, mozzarella cheese slices, and Romano cheese.

Repeat the layers until all ingredients are used, ending with a layer of sauce and cheese on top.

Bake in the preheated oven for 45-50 minutes, or until the cheese is melted and bubbly and the lasagna is heated through.

Let stand for 10 minutes before serving.
