Place peppers on an aluminum foil-lined baking sheet.
Broil 5 inches from heat (with electric oven door partially open) about 5 minutes on each side or until peppers look blistered.
Place peppers in a heavy-duty zip-top plastic bag; seal and let stand 10 minutes to loosen skins. Peel peppers, keeping stems intact. Make a slit along 1 side of each pepper; remove and discard seeds and membrane. Set aside.
Saute corn, bell pepper, and garlic in hot oil in a large skillet 5 minutes or until tender. Remove from heat. Stir in cheese and next 5 ingredients; spoon evenly into peppers. Close peppers, and place on a lightly greased baking sheet.
Bake at 350° for 20 minutes or until thoroughly heated. Serve immediately.
