Wash the king prawns and pat them dry. Heat the oil in a pan and fry the prawns for about 5 minutes. In the meantime peel garlic and cut into thin slices. Wash parsley, dab dry and cut into fine strips.
Deglaze the prawns with lemon juice. Add lemon zest, parsley and garlic and steam briefly. Season with salt and pepper and arrange on plates. Italian white bread tastes good with it.
