1Preheat oven to 350 degrees F (175 degrees C). Grease two 5x7-inch casserole dishes.
2Stir cream-style corn, whole kernel corn, Cheddar cheese, eggs, butter, flour, bell pepper, sugar, salt, and black pepper together in a large bowl; divide between prepared casserole dishes.
3Bake in the preheated oven until a toothpick inserted into the center of either casserole comes out clean, about 45 minutes.

Cook's Note:
If you want to cheat. use a can of whole kernel corn mixed with red and green bell peppers (such as Green Giant(R) Mexicorn(R)) instead of whole kernel and you got green and red pepper already. Though I find this to be rather skimpy on the peppers.
