Add shelled shrimp or chicken strips and toss to coat; set aside. Heat large wok or skillet over medium-high heat; add1 tb of oil and all of the vegetables. Stir fry until tender-crisp, about 3 minutes. Remove vegetables and set aside. Add walnuts to wok and saute until lightly browned. Add a bit more oil if necessary. Add water chestnuts and saute for 1-2 minutes longer; combine walnuts and water chestnuts with reserved vegetables and set aside. Heat remaining oil until very hot. Remove shrimp or chicken from marinade, allow excess to drip off, and reserve marinade. Stir-fry shrimp or chicken strips until cooked through, 3-4 minutes. Add chicken broth and reserved marinade. Cook until bubbling; return vegetables, walnuts and water chestnuts to wok. Toss and heat through. Stir in tarragon and serve immediately over steamed rice or crisp noodles.
