Beef Stir-Fry with Peanut Sauce

Directions

1. In a small bowl, combine cornstarch and water until smooth. Stir in peanut butter and 3 tablespoons soy sauce; set aside.
2. In a large skillet or wok, heat oil over medium-high heat. Add beef, pepper and remaining 1 tablespoon soy sauce. Cook and stir until meat is no longer pink, 4-6 minutes; remove and keep warm. Add peppers, bamboo shoots, carrot and pepper flakes; cook and stir until peppers are crisp-tender, 2-3 minutes. Add garlic; cook 1 minute longer.
3. Stir cornstarch mixture and add to pan. Bring to a boil; cook and stir until thickened, about 1 minute. Return beef mixture to pan. Serve with rice.
