Heat a large nonstick skillet coated with cooking spray over medium-high heat until hot; add pork strips, and sauté 2 minutes. Remove pork from skillet. Add broccoli and sliced bell peppers to skillet, and stir-fry 2 minutes. Stir in onion, ginger, and garlic. Cook 2 minutes, and return pork to pan. Combine chicken broth and next 5 ingredients (broth through crushed red pepper), and stir with a whisk. Add to pork mixture. Reduce heat, and simmer 4 minutes or until sauce thickens. Serve over rice.
