For the dressing mix yoghurt and lemon juice. Season to taste with salt, pepper and sugar. Wash the dill, dab dry, put something aside for garnishing. Pluck the dill flags from the stems and cut them finely.
Wash the cucumber, peel into strips, halve, core and cut into thin slices. Mix cucumber and dressing and let it soak through. Clean and wash spring onion and cut into longer pieces.
Wash the meat, dab dry and cut into 6 pieces. Halve the ham lengthwise and wrap around the meat. Put meat and spring onion alternately on 2 skewers. Heat the oil in a coated pan and fry the skewers in it for 6-8 minutes, turning from time to time.
Garnish cucumber salad with dill. Sprinkle the skewers with some pepper.
