How to Make It
Place a 12-inch ovenproof nonstick skillet over medium-high heat. Coat pan with cooking spray. Add chopped bell pepper and mushrooms; sauté 3 minutes. Add sausage, salt, and pepper; reduce heat to medium-low, and cook 1 minute.
Combine egg substitute and half-and-half; carefully pour over sausage mixture. Cover and cook 6 minutes. (Frittata will be slightly moist on top.) Sprinkle with cheese.
Broil 1 to 2 minutes or until cheese melts. Cut into 8 wedges.
