A chicken version of the Philly cheesesteak favorite, this sandwich is served open-faced, hot, and perfect for a filling lunch or quick weeknight dinner.
Preheat oven to 350 degrees F. Sprinkle the Southwest seasoning over the chicken. Heat olive oil in a large skillet over medium heat. Cook the chicken for about 5-7 minutes on each side, set aside. Cook onions and peppers in same skillet. Add the shredded chicken back to the skillet and cook until heated through.
