Blend cracker crumbs and melted butter thoroughly and press evenly on bottom and up the sides of a deep 9-inch pie pan, reserving 1/4 cup for top.
Saute green pepper and onion in melted butter until onion is transparent. Blend in flour and cook until bubbly. Add milk, all at once stirring constantly until thickened. Add corn, salt, sugar and eggs. Mix well. Pour into crust and top with reserved crumbs.
Bake for 35-45 minutes at 400 degrees or until knife inserted in center comes out clean.
NOTE: Grandma used about 2-3 cups of frozen corn from her garden instead of the two cans listed. Delish!!!
