Preparation Preheat broiler. Toss bell peppers, tomatoes, onion, and garlic with oil and coriander in a large roasting pan and broil about 4 inches from heat until edges of vegetables are charred, about 7 minutes. Stir vegetables, then broil until vegetables are tender, about 3 minutes more. Purée vegetables with any juices from pan in batches in a blender until smooth. Stir in remaining ingredients except mint. Cool soup, uncovered, 30 minutes, then chill, covered, until cold, at least 2 hours. Just before serving, stir in mint. Cooks' notes:· To chill soup quickly, set bowl with soup in a larger bowl of ice and cold water and stir until cold. · Soup can be made 2 days ahead and kept chilled, covered.
