I add a packet of onion soup mix to the hamburger along with the uncooked rice. Brown the meatballs, drain, place them into a dutch oven(mine has an enamel interior finish). As for the sauce some beef broth, a canned of fire roasted diced tomatoes and can of Contidina tomato sauce. Simmer until rice is done. I served them with mashed potatoes and a veggie.
Sometimes I add cut cabbage to the pot and make Deconstructed cabbage rolls
