Crush cereal slightly. Set aside. In large bowl, beat egg until foamy. Add cereal, salt, pepper, Worcestershire sauce, onion, mushrooms, and broth. Beat well. Add ground beef; mix only until combined. Shape into 6 patties, about 3/4 inch thick. Place in well greased or foil-lined shallow baking pan.
Bake in 375 degree oven about 25 minutes for medium doneness. Shorten or lengthen cooking time according to preference. Serve on toasted buns or as burger-steaks.
