Preparation / Directions:
1. Coat a large nonstick skillet with cooking spray; place over medium-high heat until hot. Add kielbasa and onion; saute 2 minutes. Add mushrooms and next 5 ingredients; saute 2 minutes. Add egg substitute and cheese; cook 10 minutes or until egg substitute is set, stirring occasionally. 2. Warm tortillas according to package directions. Spoon about 1/2 cup egg mixture down center of each tortilla; roll up.
Make-ahead Tip: Fill all tortillas with egg mixture; roll up, and let cool. Wrap cooled sandwiches, individually, in heavy-duty plastic wrap. Store in refrigerator up to 4 days or freeze up to 1 month. Allow frozen sandwiches to thaw overnight in refrigerator. Microwave refrigerated sandwiches, still wrapped, at HIGH for about 45 seconds or until warm, turning once.
