Chicken Breast with Cheddar Cheese Sauce

Chicken Breast with Cheddar Cheese Sauce
1/4 cup butter
2 Tablespoons flour
1/2 cup cheddar cheese, cubed
salt, pepper, and dry mustard powder, to taste
cooked chicken breast (1-2)

Melt the butter in a small saucepan over medium heat. Whisk in the flour until combined. Stir in the cheese, allowing it to melt. Season to taste. If desired, this sauce can be thinned out with a little milk or cream, which I would recommend adding before the cheese if possible. Spoon over chicken breast before reheating to retain moisture, or add halfway through the cooking time. 

This is a super fast cheddar cheese sauce - sort of like one that would be used to create a macaroni and cheese casserole, only thicker. The butter provides a lot of moisture for the chicken so it does not dry out, and the cheese creates a flavorful topping. Multiply the sauce as needed for more chicken breasts.
