Don't bother with gazpacho. Make salmorejo instead. It's a sort of thicker version that you eat from a smallish glass with a teaspoon, sprinkled on top with slivers of jamon (I prefer crispy bacon meself!) and chopped hard-boiled egg. The Andalucians eat it with some little breadsticks. I've just remembered that you avoid carbs, so this is not for you, as it relies for its texture on bread. Sorry about that. I think I've posted my salmorejo recipe before. It's a real treat as a starter or a tapa. I remember eating it in a little bar in Granada, with a view of the Alhambra on the hillside above. Beat that!
