Wash the potatoes thoroughly and cook in plenty of boiling water for about 20 minutes. In the meantime peel and finely dice the onions. Cut the bacon into fine cubes as well. Drain the potatoes, rinse them under cold water and let them drain. Peel off the skin.
Cut potatoes into slices. Heat 1 tablespoon of oil in a pan. Leave the bacon in it until crisp. Add half onions. Add stock and vinegar, season to taste with salt and pepper, heat up briefly. Pour hot marinade over the potatoes and mix everything well. Let the potato salad cool down for at least 1 hour and let it soak through. For the meatballs, knead minced meat, remaining onions, breadcrumbs, mustard and egg. Season with salt and pepper. Shape into 12 small meatballs.
