Cheesy Hamburger Casserole

I posted a similar recipe here, but I think I like this one much better.
The cast and crew of this dish:
1/2 of a chopped onion
1 lb ground beef or turkey
1 (15oz) can tomato sauce
2 c uncooked macaroni
1 can cheddar cheese soup.

Cook macaroni per package instructions. Brown the ground meat and onions in a skillet. Pour off excess grease. Stir in tomato sauce and simmer 10 min.

Pour meat and macaroni in a casserole dish and mix well. Pour cheese soup over the top and bake at 400 x 20 min.

**I added a garlic clove and bell pepper to the hamburger meat.
Then I topped the casserole with shredded cheese. I think a can of tomatoes would be good too.
