Cheese Sauce

A favorite meal at our house is a Baked Potato Bar.  One thing we like to put on them is cooked broccoli with cheese sauce!

2 tablespoons butter
2 tablespoons featherlight flour
1/2 teaspoon salt
2 cups milk
2 cups cheddar cheese, shredded

Melt butter in a saucepan.  Add salt and flour and whisk for 1 minute, until flour is heated through.  Stir in milk.  Cook on medium, stirring constantly until sauce thickens.  Add cheese and stir until melted.  Take off heat.
