Start by preparing the meatballs; in a bowl, combine the ground beef, egg, breadcrumbs, and chopped parsley. Season with salt and pepper and knead the ingredients together with your hands. Let the mixture rest for about 30 minutes in the refrigerator. While the dough rests, slice the onions. Melt the butter in a nonstick pan, add the sugar and sliced ​​onions. Cook until caramelized. Drizzle with balsamic vinegar and let it evaporate. Keep warm. Remove the meatball mixture from the refrigerator and, using wet hands, shape the meatballs. Heat plenty of oil in a nonstick pan and brown the meatballs on all sides until cooked through.
Once the meatballs are cooked, cut the rolls into slices, spread them with Igor’s Gorgonzola Dolce, then place 4 meatballs on each roll and the caramelized onion on top.
Serve immediately!
