I can't think of anything yummier on a cool fall night!

1 bell pepper, chopped
1 stalk celery, chopped
1 can golden mushroom soup
1 can cream of celery soup
1 can Ro-Tel tomatoes, diced
1 lb. crawfish tails or shrimp
1 stick butter

Saute onion, bell pepper, and celery in 1 stick of butter. Add remaining ingredients. Do not add water. Simmer and serve over rice.
