I made King Ranch Casserole, but with beef fajitas. I had a frozen bag of cooked strips, which I thawed in microwave and chopped the strips into pieces. Put in iron skillet, added onions and green peppers (frozen), can of ro-tel tomatoes and chiles, cream of mushroom soup, and grated cheese. (Low carb version. Left out corn tortillas.) Topped with sliced black olives and baked in same skillet for less cleanup. Will do that again.
