In a large bowl, combine the first five ingredients. Add the green beans; toss to coat. Transfer to an ungreased 1-qt. baking dish. Cover and bake at 350° for 20 minutes.
Meanwhile, in a large skillet, saute the onion, green pepper and garlic in butter until tender. Sprinkle over beans. Top with cheese. Bake, uncovered, for 3-5 minutes or until cheese is melted. Yield: 4-6 servings.
