Peel and finely chop the onion. In a saucepan, heat the oil. After a moment, add the onion. Fry for a few minutes, stirring occasionally.

Clean the meat and cut it into smaller pieces. Then add the meat to the onion. Fry again for a few minutes, stirring and flipping the pieces occasionally.

When the meat loses its raw color, add the passata, a ball of allspice, bay leaf, and a pinch of salt and pepper. Mix well. Simmer covered on low heat for about 5-10 minutes, stirring occasionally.

At the end, add the drained beans and heat for a moment.

Serve on a plate.
