Cook the hamburger with the onions and garlic until onions are soft and hamburger is well browned. Then add in the tomato sauce ( or tomato sauce/paste) and as much water as needed to make a nice sauce. Cook the sauce for a few minutes until boiling.

Add in your cooked pasta. This time I am using shells, but most times I use elbow macaroni. Just use what you have, penne also works well for this dish. Mix all together well and then pour into 9 x 13 casserole dish and cover with cheese.

Cover with foil (be sure to spray your foil with Pam or some kind of non stick spray so it won't stick to the cheese when baking.)

Place in a 350 oven and bake for approximately 30 to 40 minutes. When you can see the bottom all bubbly and you are sure it has been heated all the way through and the cheese is melted and all gooey, then you are done.
