Tomatoes need to be deseeded and peeled. Peeling you can do by dipping the tomatoes in hot water for half a minute or so. After this, you can slip the skin right off. De-seeding takes effort. You could decide not to deseed
Chop all the ingredients, and place in a blender, little by little, until all ingredients are blended into a chunky soup
You could sieve the mass to get a smooth soup, or serve it with a little structure.
Add water to create the thickness you like (Not that adding water will also water down the flavor of the soup)
Cool the soup in the fridge until really cold (2 hours typically)
