Cut the cucumber, spring onions and red pepper into small pieces.
Put the tomatoes in bowl and pour over hot water. After two minutes, remove their skin carefully.
Put the tomatoes with the garlic into a liquidizer and whiz until smooth. Press it through a sieve, if you like to remove the seeds.
Put the soup back into the blender and add the chopped vegetables, herbs, lemon juice and oil. Blend again, but only for a few seconds to have a course texture.
Season with salt and pepper to taste (you can add a pinch of cayenne pepper too if you'd like it spicy).
Transfer to a bowl and chill for at least 30 minutes.
Serve with the chopped vegetables, herbs – and some croutons if you like.
