Peel and dice the cucumber and add it to the pitcher.
Wash the tomatoes, roughly cut them, and add to the pitcher. Some people like to blanch them and peel them, but I prefer them raw and with the peel. Both options work.
Chop the onion and garlic and add it to the pitcher.
Wash the pepper, cut it roughly and add it.
Add the salt, vinegar, bread (if using it) and ice.
Blend everything together. I like to use a handheld blender, but a regular vase blender will work well too.
Add the olive oil and blend a bit more.
Since we added a bit of ice, you can serve it immediately. But it will be even more delicious after it hangs out in the fridge for a couple of hours.
When we have guests I reserve a bit of each of the vegetable ingredients, and chop it. It makes for a prettier and more interesting presentation.
