Cheesy Chicken Broccoli Shells

8 oz pasta shells
12 oz broccoli florets
1 pound chicken breast, cooked and cut into bite sized pieces
2 tablespoons butter
¼ cup flour
2 cups milk
2 cups grated sharp cheddar cheese (extra sharp would be even better)
½ teaspoon onion powder
½ teaspoon garlic powder
salt and pepper to taste

Instructions
In a large pot bring water to a boil and add the pasta. Cook according to package directions. Add the broccoli to the boiling water the last 3 minutes of cooking. Drain and set aside.

In the same pot, add the butter and melt over medium heat. Whisk in the flour and cook for about a minute to create a roux. Slowly whisk in the milk and cheese and bring to a boil over medium high heat until it starts to thicken.

Add in pasta shells, broccoli, and chicken and toss to coat in the sauce. Serve immediately.
