Place all the prepared vegetables and olives in a food processor or blender.
Add the cumin, sherry vinegar, bread, olive oil and about 200ml of water.
Add a pinch of salt and blend until very smooth (at least 5 minutes of blending).
Check the seasoning and add more salt if necessary.
If you dont like bits in your gazpacho you can pass it through a sieve at this stage.
Serve in a bowl with a few ice cubes, croutons, sliced olives and a few drops of olive oil, or serve in a cocktail glass with an olive on a skewer and a few drops of olive oil.
