Cozy Comfy Cheesy Chicken

When your first snow of the season is in October, you need warm bubbly comfort food. This casserole was easy to toss together especially when I had precooked chicken already chopped in the freezer and a bag of frozen broccoli standing by. So basically make a sauce, stuffing, stir it, sprinkle it, into the oven it goes!
This was in a 9 x 13 pan and there was only one serving left as a left over. You could say it was a hit. Looks like we'll need more cozy comfort food as winter us upon us! Brrr.

Broccoli Cheese Chicken and Stuffing

1 lb uncooked boneless skinless chicken breasts, cut into very small cubes (or 2 cups cooked chicken breast)
12 ounce bag broccoli florets
6 oz box chicken stuffing mix
1 1/4 cup fat free, reduced sodium chicken broth
2 cups milk
2 tbsp cornstarch
1 cup fat sharp cheddar cheese
1 tsp garlic powder
1 tsp onion powder
2 tsp yellow mustard
1/2 tsp kosher salt, divided
1/2 tsp black pepper, divided

Instructions
Preheat oven to 400F. Grease a 13x9 pan with cooking spray. Set aside.
Heat a large skillet over medium-high. Season chicken with 1/4 tsp each of salt and pepper. Coat skillet with cooking spray and sear chicken on both sides until browned, about 2 minutes each. Transfer chicken to a plate. Remove skillet from heat. (Skip this step if using pre-cooked chicken)
In a medium bowl, mix together chicken broth and stuffing mix. Set aside while you prepare the rest of the recipe. The stuffing cubes should absorb nearly all of the broth after a few minutes.
Chop broccoli into bite-sized pieces. In the cooled skillet, whisk together almond milk, cornstarch, garlic powder, onion powder, mustard, and remaining 1/4 tsp each of salt and pepper. Whisk well until combined, then return skillet to medium-high heat.
Continue whisking until the sauce starts to bubble and thicken, about 5 minutes. Once the sauce is pretty thick, remove from heat and whisk in cheese. Continue whisking until the cheese has fully melted into the liquid. If you like well done broccoli, add it into the sauce, return to heat, and cook for about 2-3 minutes.
Stir broccoli and chicken into the sauce. Pour into prepared pan and evenly distribute the broccoli and chicken. Sprinkle stuffing mixture in a layer over the top.
Bake uncovered for 30-40 minutes, or until stuffing is browned on top.
