My wife makes the hamburger kind of like meatloaf but without the ketchup and mustard and bread crumbs. After the meat is mixed she mixes in rice that has been cooked. Then stuffs the peppers that have been cooked for a very short time in water to soften them so they won't split when stuffed. Then they go in a deep baking dish or casserole with homemade tomato sauce poured over them so it comes up about 3/4 of the depth of the dish and bakes them in the oven.
