Rice supper casserole

1 cup uncooked rice
1 can Cream of mushroom soup
1 can green beans
1 med onion Chopped
1 cup chopped celery
2 cups chopper meat (chicken, turkey, ham or pork roast)
1 tbs olive oil
1 small can mushrooms (optional)

Preheat oven to 375
Cook rice (I have used brown and white rice. They both worked)
In a skillet heat oil on med-high Sautte onions and celery about 5 minutes add mushroom soup, meat, green beans, and mushrooms. Simmer for about 5 minutes. Combine these with the rice in a casserole dish and bake for 30 minutes
Salt and pepper to taste.

This is a simple recipe for those left-overs. My kids loved it.
