PREPARATION:
- Cook spaghetti according to package directions; drain and keep warm. Meanwhile, combine tofu and soy sauce in medium bowl; set aside. Combine vegetable broth and cornstarch in cup until smooth.
- Heat oil in large nonstick skillet or wok. Add celery, broccoli, bell pepper, green onions, orange peel and ginger. Stir-fry until vegetables are crisp-tender, about 4 to 5 minutes. Stir cornstarch mixture and add to vegetable mixture; bring to a boil, stirring constantly until mixture is slightly thickened, about 1 minute.
- Gently stir in tofu mixture; cook until heated through, about 1 minute. Serve over spaghetti. Garnish with orange slices.
