Wash the meat and dab dry. First cut into strips of about 1.5 cm, then into pieces (about 3 x 3 cm). Put on skewers.
Wash 1 lemon thoroughly, finely grate the peel. Halve lemon and squeeze juice. Wash parsley, shake dry and pluck off leaves. Chop the leaves finely, except for a little to garnish.
Heat the oil in a very large frying pan. Fry the meat skewers for 3-4 minutes on each side. Then season with salt, pepper, sugar, lemon zest and juice.
In the meantime, bake bread in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 6-8 minutes. Wash the remaining lemons, grate dry and cut into slices.
Mix sour cream with chopped parsley, arrange and garnish with parsley. Remove bread from the oven. Arrange skewers on plates, garnish with lemon slices. Add bread and sour cream.
