Preheat your oven to 375 degrees. Spray a 9x13 dish.
In large bowl, stir your ground beef, egg, soy sauce, Worcestershire sauce, chili powder, onion powder and garlic powder.
In another bowl, whisk your cream of mushroom soup and chicken broth until all the lumps are gone.
Add your rice and stir well. Pour into the prepared dish.
Using a small scoop or tablespoon form your meatballs and drop them into the rice mixture, arranging them into a straight line. I had 25 meatballs.
Cover the dish with foil and bake for 40 minutes.
Remove the foil and bake an additional 15-20 minutes. The meatballs need to be cooked through and most of the liquid absorbed.
