Grilled corn muffins are so delicious. Start with corn muffins from Foods By George that are a little grainy like really good corn muffins should be, not dry or crumbly.
Wrap frozen muffin in a paper towel and microwave on high for about 40 seconds. Let sit for a minute to distribute the heat. Carefully slice muffin in half with a sharp knife. Then, coat the grill with lots of butter and cook (cut sides down) on medium until golden brown, about 2 minutes.
