Tear bread into small pieces; transfer to medium bowl and cover with cold water. Soak until bread is saturated, about 15 minutes. Squeeze water from bread, discarding soaking water.
In bowl of blender or food processor, add bread, tomatoes, cucumber, bell pepper, garlic and ¼ cup water. Blend until well combined, about 1 minute. With motor running, add oil in steady stream until well blended. Stir in vinegar; season with adobo.
Strain pureed soup through small-hole strainer into soup terrine, pressing firmly to pass all liquid through strainer; discard any solids. Cover terrine; transfer to refrigerator. Chill at least 1 hour, or up to 48 hours.
To serve, divide soup evenly among serving bowls. Garnish with tomatoes, onions, peppers, eggs and/or toasted bread, if desired.
In our Gazpacho recipe, we call for peeled tomatoes. However, peeling tomatoes with a vegetable peeler is no easy task: the tomato’s soft flesh tends to bruise and squish as the peeler hacks away at the skin. To peel the tomato while keeping the flesh intact, try this chef trick: Bring a pot of water to a boil. With the tip of your knife, make an “x” in the base of the tomato. Plunge the tomatoes into the water; let boil 30 seconds. Using a slotted spoon, immediately transfer tomatoes to bowl of ice water to chill. This “blanching” and “shocking” process detaches the tomato’s skin from its flesh. Next, use your hand to easily peel off the skin.
