Preheat oven to 350°F.
In a medium skillet, melt butter. Add bell pepper and onion; cook over low heat about 5 minutes or until slightly soft.
In a large bowl, combine cans of corn, beaten eggs, cracker crumbs, milk, cooked vegetables, salt and pepper.
Pour mixture into a well-buttered 2-quart casserole or baking dish.
Bake 60 minutes (or until set in the center).
Let sit about ten minutes before serving.
