STUFFED PEPPER CASSEROLE

In a large skillet cook the ground beef, breaking apart. Once it is mostly cooked add in the onions and bell peppers and cook for 5-10 minutes until they start to soften.
Add the garlic to the beef mixture and cook for a minute or two, just until you can start to smell it.
Sit in the rest of the ingredients, except the cheese, and bring the mixture to a boil.
Cover and reduce the heat to a simmer and cook for about 20 minutes, stirring half way through.
