Place the lentils in a sieve, rinse and soak in cold water for at least 3 hours. Drain the lentils in the sieve, collecting the soaking water. Set aside 3 tablespoons of the lentils. Finely puree the rest of the lentils in the universal chopper or with a hand blender. Add some soaking water if necessary. Peel onion and garlic, dice finely and add to the lentil puree.
Mix flour and baking powder and knead with the puree to a dough. Season to taste with salt, coriander, cumin, chilli powder and turmeric. Put the dough in a cool place for about 30 minutes.

Mix sugar, 1/2 tsp salt, 3 tsp oil and vinegar and mix with the vegetable cubes. Wash parsley, dab dry and cut into fine strips, except for a few leaves for garnishing. Add to the salad. Rinse mint, dab dry and chop. Mix mint and yoghurt and season with salt and pepper. Form 24 small balls from the lentil dough.
