Tofu and Vegetable Stir-Fry

Place tofu pieces in a small bowl. Pour teriyaki sauce over cubes and stir to coat. Let sit 30 minutes to marinate at room temperature. Meanwhile, prepare vegetables as described above. Heat 1 tablespoon peanut oil over medium-high heat in a wok or large sauté pan. Add garlic, onion, and black pepper and stir-fry about 1 minute. Raise heat to high, and add marinated tofu (and any remaining teriyaki sauce within the bowl), chicken broth, and soy sauce; stir-fry 1 minute. Add broccoli, mushrooms, red pepper, and water chestnuts. Stir-fry 2–3 minutes until desired crispness of vegetables is reached. Serve each portion over 2/3 cup hot, cooked brown rice.
