This is Antigone's favorite meal!
1 lb ground beef
1 box mostacolli pasta (or penne pasta is fine)
1 jar spaghetti sauce (I like Bertolli's)
1 can cheddar cheese soup (you can also use any form of cheese soup, Nacho Cheese, Fiesta Cheese, etc.)
Boil pasta. Brown and drain the ground beef, season with garlic salt. Mix beef with spaghetti sauce, cheese soup and a few pinches of oregano. Bring sauce to boil and then simmer until pasta is ready (I always cook them simultaneously). Drain pasta and mix with sauce in a large bowl. Place pasta in layers in a 9x13 baking dish, covering each layer with mozarella. Cover the top with mozarella also. Spray one side of aluminum foil with Pam cooking spray, cover the dish and bake for 20 min (or until boiling) at 350 degrees.
