This stir fry is delicious with tender strips of beef, sweet fresh veggies and a spicy beef sauce. I like to marinate my stir fry meat before cooking to add an extra layer of flavor. I like to use Dale's Liquid Steak Seasoning, but it can be difficult to find. If you can't find this product, substitute 1 1/2 tbs. soy sauce plus 1 tbs. Worcestershire Sauce. It's not the same but close enough. The heat level of this dish is just right for me, but you may adjust the amount of cayenne pepper per your taste.
