In a small bowl, combine the corn and peppers. In another bowl, whisk the oil, garlic, cumin, chili powder and salt. Drizzle over vegetables and toss to coat. Place in a single layer in an ungreased 15x10x1-in. baking pan.
Bake, uncovered, at 425° for 10-15 minutes or until peppers are tender. Cool slightly. Transfer to a serving bowl; stir in the black beans and cilantro. Serve with tortilla chips.
