Karen'S Casserole - cooking recipe

Ingredients

2 cups boneless skinless chicken breasts, cut into bite-sized pieces. Approx 1lb of meat
1 onion, chopped
1 cup celery, chopped
8 ounces fresh mushrooms, sliced
2 tablespoons butter
3 cups cooked rice, jasmine rice works well
1/2 teaspoon salt
1 (10 ounce) can cream of mushroom soup, undiluted
1/2 cup milk
1/2 cup mayonnaise
paprika

Preparation

Preheat oven to 350 degrees F.
In large pan, brown onion, celery, mushrooms, and chicken in the butter.
Remove from heat and add all other ingredients except paprika, mix well.
Place in a greased 2-quart casserole dish. May seem a bit watery, this will go away after it's baked.
Top with paprika, to taste. I do a solid coating so the top is entirely red.
Bake for 35-40 minutes. Top should be slightly browned and casserole a bit bubbly.
