Beef and Spinach Skillet

Directions

1. In a 10-in. cast-iron or other ovenproof skillet, cook beef and onion over medium heat until meat is no longer pink; drain. Add the spinach, mushrooms, garlic salt and basil. Cover and cook for 5 minutes.
2. In a saucepan, melt butter over medium heat. Stir in the flour and salt until smooth. Gradually add milk. Bring to a boil; cook and stir until thickened, about 2 minutes. Stir in cheese. Pour over meat mixture; mix well. Reduce heat; cook, covered, until heated through. If desired, serve with biscuits.
