BBQ Chicken Crusted Cheddar Macaroni

I got this recipe idea from the Picky Palate. My neighbor had a baby, so I thought I would try it out. Unfortunately, I didn't taste any but I made the macaroni and the bbq separately for Ben and I and they tasted great.

Mac and Cheese:
2 c. uncooked elbow macaroni
1/4c stick butter
1/4c all-purpose flour
1/2 tsp salt
1/4 tsp pepper
1/4 tsp mustard
1/4 tsp Worchestershire sauce
2c milk
2c shredded sharp Cheddar cheese.

1. Heat Oven to 350 degrees.
2. Cook macaroni as directed on package.
3. While macaroni is cooking, melt butter in 3-qt saucepan over low heat. Stir in flour, salt, pepper, mustard and Worchestershire sauce. Cook over low heat, stirring constantly, until mixture is smooth and bubbly; remove from heat. Stire in milk. heat to boiling, stirring constantly. Boil and stir 1 minute; remove from heat. Stire in cheese until melted.
4. Drain macaroni. Gently stir macaroni into cheese sauce. Pour into ungreased 2-qt casserole. Bake uncovered 20-25 minutes or until bubbly. **If you decide to add the bbq, follow the directions below and add in chopped chicken before baking the macaroni**
