Quinoa, Chicken and Broccoli Casserole

I wanted to prepare an updated version of chicken divan. I thought quinoa might be a good fit for this dish. I like adding quinoa where I can because it has so many health benefits. I divided this into 1 medium sized casserole for us and a smaller one for my mom. If you don't need that much, divide the ingredient amounts by half.

3 cups cooked quinoa
3 cups shredded cooked chicken
4 cups steamed broccoli florets
1 medium onion diced,sauted
2 1/2 cups chicken stock
1 8 oz. container of pub cheese or2 1/2 cups shredded cheddar cheese
2/3 cup SOS mix(recipe below)
1 tbsp olive oil
salt and pepper to taste
tabassco to taste
1 1/2 cups Panko crumbs
1/4 minced parsley
1/4 melted butter or margarine

Spray 1 medium casserole and 1 small casserole dish with cooking spray, set aside. Preheat the oven to 350. In a medium sauce pan whisk the chicken stock, SOS mix, salt and pepper together. Turn the heat on medium high. Cook stirring constantly until the mixture begins to boil and thicken. Turn the heat off and stir in the pub cheese and the tabassco, if desired. Saute the onion in the oil in a medium skillet until translucent. Place quinoa, chicken, broccoli and onion in a large bowl. Pour the cheese sauce over all and mix well to coat. Divide the contents between the 2 casserole dishes. Toss the panko and parsley together with the meleted butter or margarine. Sprinkle over the top of both dishes. Bake for 30 minutes or until browned and bubbly.

SOS Mix
SOS Mix is a good alternative to canned cream of ______ soup. It has no preservatives, gluten, salt or artificial anything. This is a powdered base made with powdered milk, dehydrated onion and cornstarch. You can mix this base with any liquid to make sauces wherever you might add canned soup. Oh, and did I mention that this works well in your slow cooker? Here's what you need

1 1/2 cups of powdered milk
1 cup cornstarch
3 tbsp dehydrated onion flakes

Place all the above in a container, cover and shake to mix well.
To Use- add 1/3 cup of SOS Mix to 1 1/4 cup liquid.
Pour the liquid into a sauce pan and whisk in the SOS Mix off the heat.
Turn the heat up to medium/high and bring to a slow boil, mixing continuously, until thickened.
Add salt, pepper, and other seasonings or cheese to make your desired sauce.
Use as in recipes calling for a cheese sauce, white sauce, or canned soup.
