In a saucepan melt 3 tablespoons of butter then add flour. Stir and let cook for about 3 minutes. Add milk and mustard then season with salt and pepper, to taste. Stir constantly while bringing to a boil over medium-high heat and continue to cook until thickened and creamy (not quite gravy).

When consistency is reached remove from heat and stir in shredded cheese until melted.

Pour your cooked and drained pasta in a 8 or 9-inch round or square casserole dish. Top with cheese sauce and mix well.

Melt 1 tablespoon of butter in microwave and then add bread crumbs. Sprinkle mixture on top and then bake at 350°F for 25 minutes.

If needed brown topping under broiler for a few minutes.
