Trim fat from beef. Thinly slice beef across the grain into bite-size strips. Spray a wok or large skillet with non-stick cooking spray. Heat over medium heat. Stir-fry garlic for 15 seconds. Add squash and broccoli and stir-fry for 3 4 minutes or until crisp-tender. Remove from wok. Add oil to wok, then add beef and stir-fry 3 4 minutes or to desired doneness. Return vegetables to wok. Add cherry tomato halves, salad dressing and green onions. Toss to mix. Cover to heat through. Serve over hot pasta, and sprinkle with parmesan cheese.
