Place the tomatoes, bell pepper, cucumber, red onion, and garlic in a blender or food processor. Add the soaked bread, olive oil, sherry vinegar, sea salt, black pepper, and cumin. Blend for about 1 minute or until the soup achieves a smooth and creamy consistency. Adjust the texture based on personal preference by blending longer for a silkier soup or pulsing for a chunkier finish.
