Wash and chop the tomatoes. Then roughly tear or chop the bread. Add both, along with 1/2 tsp salt and 1/4 tsp pepper to a large bowl. Toss and let soak for about 20 minutes.
While the bread and tomatoes soak, peel the kiwi and onion. Then roughly chop the kiwi, onion, and persian cucumbers.
Add the tomatoes, bread, kiwi, onion, garlic, cucumbers, and 3 tbsp sherry vinegar to a blender and blend until smooth. Then, continue to blend while slowly drizzling in 1/4 cup olive oil. Taste, and adjust seasoning as you see fit (now's your chance to add more salt, pepper, or sherry vinegar).
Pour into a large container and refrigerate for a couple of hours before eating. Garnish with diced cucumber and kiwi, as well as a splash of olive oil and some flaky sea salt (if you'd like), and enjoy!
