In a medium/large pan cook ground beef seasoned with salt and pepper and chopped onions till beef is no longer pink. Add garlic cook another 2minutes. Add maranara sauce to beef and mix well, set meat mixture aside. In a pot cook rice as directed on back of the box, once rice is fully cooked add it to the meat and mix till all well blended. Take the peppers and cut the middle out, get rid of all the seeds inside and stuff each pepper with the rice and beef mixture. Stuff well to the top. Add 1/4 cup of broth or water & 1/4 cup maranara sauce to the crock pot and place the 4 stuffed peppers inside. Cook on high 3hours or until a fork can easily prick thru the peppers. Once done sprinkle each pepper with cheddar cheese and close lid. Let stand closed for 5 minutes till the cheese is all melted. Serve with Garlic toast. Enjoy.
