Combine the tomatoes, bell peppers, cucumbers, onions, garlic, salt, vinegar, and pepper in a large nonreactive bowl. Let stand until the vegetables just begin to release their juices, about 5 minutes. Stir in the tomato juice, hot pepper sauce, if using, and ice cubes. Cover tightly and refrigerate to blend flavors, at least 4 hours and up to 2 days.

Adjust the seasonings with salt and pepper and remove and discard any unmelted ice cubes. Serve cold, drizzling each portion with about 1 teaspoon extra-virgin olive oil and topping with the desired garnishes, (see top note).
