King Ranch Chicken Casserole is a Southern staple. It’s spicy, cheesy, and everything you’re craving when hunger strikes. This is a vegetarian version that uses Quorn nak'd 'chikn' cutlets.
Sauté onion and bell pepper in hot oil in a large skillet over medium-high heat 5 minutes or until tender. Stir in 'chicken' and next 7 ingredients; remove from heat.
Tear tortillas into 1-inch pieces; layer one-third of tortilla pieces in bottom of a lightly greased 13- x 9-inch baking dish. Top with one-third of chicken mixture and 2/3 cup cheese. Repeat layers twice.
