1Melt half of butter in frying pan; add peppers and onion and cook until the onion is translucent.
2Combine the eggs, canned corn, milk, remaining butter and sour cream in a large bowl, then add the cornbread mix and mix well.
3When the peppers and onions are ready, add everything into the large mixing bowl.
4Add the cheese and mix to combine it all. Pour mixture into a casserole dish of at least 1 1/2 quarts (that has been well greased) and bake uncovered at 350 degrees for 30 minutes or until the top is golden brown and looks like cornbread.
5Remove from oven and let it rest for 5-10 minutes before serving.
