Spanish Gazpacho

In a blender, combine bread, orange juice, and oil. Let stand until bread is soft, about 5 minutes. Add tomatoes, garlic, bell pepper, onion, vinegar, cumin, 1 tablespoon salt, and 1/4 teaspoon pepper. Purée until very silky and smooth, 2 to 3 minutes. Refrigerate until cold, at least 2 hours or, in an airtight container, up to 3 days. Season with more salt and pepper and drizzle with oil; serve.
