3 cups diced cooked chicken

1 cup mayonnaise
1 (6 ounce) box long-grain and wild rice, cooked according to package directions
1 cup grated cheddar cheese
pinch salt

preheat oven to 350 degrees
mix all ingredients together and pour into a greased 3-quart casserole dish. Bake for 20-25 minutes or until bubbly.
