Really enjoyed this old fashion "hotdish". I precooked the rice on the stovetop while browning the hambuger, with onions, omitted the celery altogether. Because the rice was just done when I added it to the meat and soup no additional water is needed. Also covered while baking, fast cooking rice is just not as good in this dish!only bake for 45 min. Cheese and frozen peas would be great additions. We passed the soy sauce at the table. Great comfort food, thanks for posting.
