Spinach balls (approx. 8 pieces)
Wash the spinach, cook briefly in a pan with a little water until all the liquid has evaporated. Leave to cool, chop or puree the spinach. Add the grated cheese, egg and as many breadcrumbs as are needed for the mixture to hold together. Shape into approx. 8 balls and place on a baking tray lined with baking paper.
Bake: for 15-20 mins. in the centre of an oven preheated to 180°C.
Mix all of the ingredients, season.
Cut open the pittas if necessary, sprinkle with water and toast. Spoon 1 tbsp of the yoghurt dressing into each pitta, fill with the lettuce, spinach balls and kohlrabi, drizzle each pitta with 1 tbsp of dressing and garnish with the sprouts. Serve immediately.
