Preheat the oven to 400 degree F. Preheat the grill to high heat.
Remove the cornhusks and corn silk, and place the fresh sweet corn, onion slices and red bell pepper on the grill. Grill the corn and bell pepper for 8-10 minutes, turning every 2 minutes until all sides are slightly charred.
Grill the onion slices for approximately 3 minutes per side.
When the veggies are cool enough to handle, cut the corn off the cob. Then chop the onions and pepper, removing the pepper seeds.
In an 8 X 8 inch baking dish or one-quart soufflé dish, mix all the ingredients together until well combined. Bake for 10-15 minutes until the edges are bubbly.
Serve warm with tortilla chips
If you don’t own a grill you can achieve similar results by searing the veggies in a large cast iron skillet over high heat. Make sure the skillet is piping hot before starting.
