How to make
Mix the beef mince, finely chopped onions, breadcrumbs and eggs. Form small meatballs. Bake them in the oven for about half an hour at 370°F (190 °C), or fry them until golden.
Drain out the excess fat. In a saucepan, blend the other products. Let the mixture simmer for about 15 minutes.
Put the meatballs in and leave them on the stove on low heat for about 30 minutes.
