If using fresh corn, use a sharp knife to cut the kernels off the cob. If using frozen, no need to thaw, just add a few more minutes to the cooking time. If using canned, drain the corn.
Dice the green bell peppers, a small dice just slightly bigger than the corn.
Melt the butter in a skillet over medium heat.
When the butter stops foaming, add the bell pepper. Cook for about 3 minutes, stirring occasionally.
Add the corn, sprinkle with salt and pepper and cook stirring occasionally for 5-10 minutes.
