Pour the heated milk over the roll and set aside to soak. After 10 minutes, drain off excess fluid well. Combine the roll with the meat and dried tomatoes. On a grater, on a fine mesh, grate the onion and add to the rest of the ingredients. Toss in spices, garlic and egg yolk. Mix very thoroughly. Form small patties and coat them in flour. Fry in a little hot oil, until golden brown on both sides.
