In a large skillet cook the hamburger meat along with the garlic until well done. Once completely cooked, add in 1 cup of cheese and 1/2 jar of spaghetti sauce. Mix this up and let simmer 10 minutes.
Spray a 9 x 13 casserole dish with non stick cooking spray, then take a jumbo shell and stuff with about 1 Tbsp of the beef mixture into each shell. Pour the remaining spaghetti sauce over the shells and top with cheese. This will bake in the oven for 15 minutes or until the cheese is melted.
