Skillet Beef Enchiladas

Instructions

Heat oil in 12-inch nonstick skillet over medium heat until shimmering. Add tortilla strips and fry until spotty brown, about 7 minutes; transfer to paper towel–lined plate.
Cook beef, onion, and salt in now-empty skillet over medium-high heat, breaking up meat with spoon, until browned, about 6 minutes. Reduce heat to medium and stir in enchilada sauce and 2 cups tortilla strips. Simmer until slightly thickened, about 5 minutes. Sprinkle remaining 1 cup tortilla strips, Colby Jack, olives, and scallions over top. Reduce heat to low and cook until cheese is melted, about 3 minutes. Serve with sour cream.
