Spray a skillet with nonstick cooking spray or add olive oil.
Over medium heat, saute veggies until soft. Stir in egg whites and cook to a soft scramble. Season with salt and pepper. Add turkey bacon or sausage, stirring to cook and add cheese. Stir until cheese has melted and well combined.
Transfer to flatbread. Wrap, slice and serve warm.
For a breakfast burrito and more crunch, wrap and tuck ends and return to skillet to toast.
