Prepare pasta according to package directions; three minutes before pasta is done, add broccoli florets. While pasta is cooking, heat 2 tablespoons of the dressing in large skillet over medium-high heat. Add shrimp and pepper flakes; stir-fry 3-4 minutes or until shrimp is opaque.
Drain pasta and broccoli; transfer to a serving bowl. Add remaining 1/3 cup dressing and shrimp mixture; toss well. Sprinkle with cheese and serve.
