Preheat the oil in a large pot over medium-high heat.
Brown the meat on all sides.
Add the stock or water, and the onion, mushrooms, carrots, celery and turnip.
Simmer until the vegetables are soft and the bison is tender, about 1 hour.
Add salt and pepper to taste.
If desired, add the water or cream and the uncooked rice to the stew and cook for 20 minutes longer, for full meal.
Or simply serve plain with bannock on the side.
