1. Mix first 3 ingredients until blended. Toss 1 Tbsp. with chicken. Let stand 5 min.
2. Stir-fry chicken and vegetables in hot oil in nonstick wok or large skillet on medium-high heat 4 min. or until chicken is done.
3. Add remaining dressing mixture; mix well. Simmer on medium-low heat 2 min., stirring frequently. Serve over rice.
Make it Easy: You can buy beef and chicken already cut into strips at most grocery stores. Vegetables, such as peppers, are also available pre-cut in bags in the produce section of many larger supermarkets.
Special Extra: For added crunch, sprinkle 1/4 cup chopped almonds, cashews or peanuts over stir-fry just before serving.
