Prepare meatballs by rolling uncooked sausage into 3/4 - 1 inch balls. Place garlic and olive oil in a large saute pan and cook for one minute. Add meatballs and cook till browned.
Cook the pasta in a large pot of boiling water. Strain and rinse the pasta then place in a large bowl; add meatballs. Pour spaghetti sauce and 1 cup cheese directly over the pasta and meatballs. Stir together well.
Pour pasta mixture into a greased 9x13 baking pan. Cover with aluminum foil and bake 375° for 25 minutes. Remove from the oven and top with last cup of cheese. Bake uncovered 5 more minutes, or until cheese is melted. Serve and enjoy!
