Spray a large skillet with cooking spray; heat over medium.  Add turkey and begin to brown.  Meanwhile, chop mushrooms and pepper; grate carrots. 

Add vegetables to skillet with turkey, continue to cook until beef is no longer pink and veggies have begun to soften. 

Heat a sandwich press, or another skillet.  Place one tortilla down onto hot surface; top with turkey and veggies, sprinkle with cheese, beans and corn, and cover with second tortilla; heat until golden brown, flip over to brown second side.  Cut into 4 pieces; serve with nectarines.
