Macaroni and Cheese

Melt butter in a 4 cup measuring cup (or saucepan).

Stir in flour and cook 1 minute.

Add salt, Worcestershire sauce and pepper. Gradually stir in milk.

Cook and stir until smooth and thickened, about 3 minutes.

Remove from heat and stir in 1 1/2 cups shredded cheddar cheese until melted.

Combine sauce and cooked macaroni.

Top with remaining 1/2 cup cheddar cheese and crumb mixture if desired.

Bake on a greased pan until bubbly and golden, about 5 to 10 minutes depending on oven.

Let stand 1 minute before serving and top with tomato slices.
