Chicken and Wild Rice Hot Dish

4 cups cooked chicken, diced
1 medium onion, diced and sauteed in a little butter
1- 8oz. can water chestnuts, drained and chopped
2 - 14 1/2oz. cans French green beans, rinsed and drained
1 small container of mushrooms, cleaned and chopped
1 - 10 3/4oz. can condensed cream of celery soup
1 cup real mayonnaise
1 - 6oz. box Uncle Ben's long grain and wild rice original recipe, cooked according to package directions
1 cup cheddar cheese, grated

Preheat oven to 300 degrees. Mix all ingredients together in a large bowl. Pour into greased  13x9 pan. Bake for 30 mintues or until bubbly and heated through.

** Now you can use reduced fat mayo, soup, and cheese in this recipe to lighten it up a bit. If you dont like mushrooms you can substitute some pimentos for them! Curt loved this dish when I made it!**
