Spray a large frying pan with cooking spray. Add the onions and peppers, and saute over medium high heat. Turn it down after the onions are mostly translucent, and add the broccoli and asparagus. Sprinkle some seasonings on top, and add the water when it starts to stick. Mix. Cook. When the broccoli is mostly cooked, add the quorn and some more seasonings to taste.
Serve in a large flour tortilla, with guacamole, sour cream, and salsa.
