Preheat oven to 400°. Spray or grease a 9x13 baking dish generously on bottom and sides.

Place chicken broth 1/2 cup milk in a saucepan; bring this to a low boil. In a separate cup, combine remaining milk with flour, salt, pepper, Parmesan cheese and poultry seasoning. Stir well, to remove lumps. Whisk this into boiling milk mixture. Whisk until it thickens and forms a smooth sauce. Pour sauce into a large mixing bowl. Add 1 cup of water, crumbled bacon and uncooked quinoa; mix well.Pour mixture into prepared baking dish.

Slice chicken into thin strips. Lay strips over the surface of the quinoa sauce. Lightly sprinkle pieces of chicken with seasoning salt and Parmesan cheese. Place casserole in 400° oven. Bake for 30 minutes, uncovered.

While casserole is baking, prepare broccoli. Place broccoli florets in a pan of boiling water for 1 minute. Remove, drain, then immediately run it under cold water (this will ensure the broccoli remains a bright green color when baked). Drain and set aside.

After casserole has cooked for 30 minutes, remove from oven. Give it a good stir. Place casserole back into the oven for 15 additional minutes until it is thick and creamy. Add broccoli florets; stir to combine and distribute broccoli throughout casserole. You want the sauce to be thick, smooth and creamy, so if you need to add a tiny bit of extra water to achieve this, do it at this time (optional).

Garnish the top of the casserole with grated Gruyere cheese. Place casserole back into oven for about 5 minutes, to melt the cheese. Remove from oven, serve and enjoy!
