Hollow out the avocado and dice the meat - immediately drizzle with the juice of half a lemon so that it does not discolour. Then chop up with the hand blender.
Finely dice the onion and garlic cloves and add to the avocado together with the low-fat yoghurt. Puree until a cream is formed.
Season to taste with salt and white pepper. The sauce should always be made fresh and not stand too long, as the avocado can become unattractive in color.
This sauce comes from Spain and is an ideal companion for grilled meat.
