For the salsa, put the cucumbers in a sieve and let them drip off. Peel and finely dice 2 onions. Heat 1 tablespoon of oil, fry the onion cubes lightly. Remove from the stove. Chop the cucumbers finely. Wash parsley and shake dry, pluck off leaves and chop.
Mix half onion cubes, cucumber, parsley and 1 tablespoon mustard.
For the meatballs, knead the minced meat with the remaining onion cubes, 1 tablespoon mustard, curd cheese and 6 tablespoons Panko. Season with 1 tsp salt and 1⁄2 tsp pepper. Form 8 meatballs from the mixture.
For the purée, clean and coarsely dice the rutabaga (see page 65). Peel, wash and halve the potatoes. Cook both in boiling salted water for about 25 minutes. Peel carrots and parsley root (see
pages 64 and 65) and cut into pieces. After about 10 minutes add to the potatoes and cook. Warm up the milk and butter. Drain vegetables and potatoes. Pour in the milk mixture and mash everything to a chunky puree.
Season to taste with salt and nutmeg.
Heat 4 tablespoons of oil in a large frying pan. Fry the meatballs for 4-6 minutes on each side. Cut remaining onions into rings. Season with salt and turn in 4 tbsp Panko. Remove the meatballs from the pan and keep warm.
Fry the onions in hot frying fat until they are glassy and turn until the crumbs are golden brown. Arrange the meatballs with onions, puree and relish.
