Tofu takes on the flavors you mix with it. In this case, a sweet-and-sour sauce does the trick.
For sauce, in a small bowl stir together sweet-and-sour sauce and ground red pepper. Set aside.
Pour cooking oil into a wok or large skillet. (Add more oil as necessary during cooking.) Preheat over medium-high heat. Stir-fry green onions and sweet pepper in hot oil for 1 minute. Add fresh pea pods (if using); stir-fry for 1 to 2 minutes more or until vegetables are crisp-tender. Push vegetables from the center of the wok.
Add sauce to the center of the wok. Cook and stir until sauce is bubbly. Add tofu, orange sections, and thawed frozen pea pods (if using). Gently stir all ingredients together to coat with sauce. Cover and cook for 1 to 2 minutes more or until heated through. Serve immediately with hot cooked rice. Sprinkle with peanuts. Makes 4 servings.
Prepare vegetables; cover and chill up to 4 hours.
