2 tablespoons low sodium soy sauce
1 teaspoon Worcestershire sauce
1/2 teaspoon ground ginger
1/2 teaspoon black pepper
2 tablespoons oyster flavored sauce, optional

Cut the steak into bite sized pieces.
Place vegetables in the bottom of the crockpot; place the beef on top of the vegetables. Add the rest of the ingredients over top.
