New York Deli Mac & Cheese

1          lb         cavitappi pasta

3          Tbsp     butter

3          Tbsp     flour

1          c           chicken stock

2          c           milk

¼         c           spicy brown deli mustard

1 ½       c           shredded sharp white cheddar cheese (about 2/3 lb.)

1 ½       c           shredded Swiss cheese

½         lb         pastrami, chopped

4          slices     rye bread, toasted and finely chopped

Boil the pasta to al dente in a pot of salted water. Drain it well and pour into a 9x13 baking dish.

In a saucepan, melt the butter and then whisk in the flour. Cook for one minute. Add the stock, milk, and mustard and heat until bubbling. Stir in 1 cup of each cheese until the cheese is fully melted and the sauce is smooth. Fold in the chopped pastrami. Spread the sauce over the pasta and stir to combine.

Top the pasta mixture with the remaining cheese, then the chopped rye bread. Place the pan under the broiler on medium heat, and watch carefully for the bread to brown and the cheese to melt.
