This is a really quick, easy dish. We usually just have this and some bread for dipping but you could make it a first course to a larger meal, too.
Melt butter in large pot.
Add chopped onion, celery, and bell pepper and saute until tender, about 5 minutes.
Add flour to vegetables and stir to coat. Cook for about one minute.
Add corn (including liquid), chicken broth, cream, and shredded chicken.
Reduce heat and simmer 20 minutes. Add salt and pepper to taste.
