Cut the bread roll with the crust into cubes and soak in a little milk. Sauté the onions and garlic and let them cool.
Squeeze the milk out of the rolls, then mix all the ingredients carefully and use them to form meatballs of the desired size. Fry in a mixture of sunflower and olive oil.
The 2 tablespoons of pesto give the meatballs a wonderful taste.
