Chicken, Mushroom, Broccoli, and Rice Casserole

They say your taste buds change every 7 years. I don't know how true that is but John and I used to hate mushrooms but now we love them. Every once in a while a good casserole on Sundays is just what you need. My family loved this.

Chicken, Mushroom, Broccoli, and Rice Casserole

by For the Love of Cooking

1 T olive oil
1/2 onion
1 lb mushrooms quartered
1 stalk of celery diced
1 (4 ounce) box of Farmhouse Long Grain & Wild Rice (or your favorite brand), prepared per instructions
2 cooked chicken breasts, cubed (I use left over roasted chicken meat)
1 6-8 oz can of sliced water chestnuts, diced (optional, John liked them but I didn't)
1 cup of broccoli florets
1 10 3/4 oz can of Cream of Chicken soup
1 10 3/4 oz can of Cream of Celery soup
1/4 cup light mayonnaise
Salt and pepper to taste

Preheat oven to 350 degrees. Prepare rice per instructions. In a heated pan add 1/2 tbsp oil and cook mushrooms until golden brown - remove from pan. Add the other 1/2 tbsp of oil to the pan and cook onions and celery until soft. Using a steamer, steam broccoli until just fork tender, then cool. In a large bowl, combine all ingredients and mix well.

Put into a baking dish and heat uncovered for 30 minutes. Let cool for a few minutes prior to serving.
