Cut corn kernels off the cob into a bowl so they don’t fly everywhere.
Add kernels to a large skillet with a few tablespoons of butter and cook until kernels start to brown over medium heat (about 8-10 minutes).
Meanwhile, dice onion, peppers, scallion, garlic, and jalapeno. Add veggies to pan and cook for a few more minutes to mix veggies and lightly cook the veggies.
Add all the veggies to a large bowl along with other ingredients (just half of the cheese). Stir together.
Add to an 8×8 baking dish and top with remaining cheese.
Bake at 350 degrees for 15-20 minutes until cheese is bubbling.
