Finely chop the onion and garlic.
Heat the olive oil and add the onion and garlic.
Fry the onion until golden.
Add the meat and stir well until the meat dries out any fluid, make sure to mix all the time so the meat will not stick and burn.
When the meat is dry, add the white wine and cook until all the liquid evaporates.
Add the white beans with sauce.
Add tomato paste with a little water and mix well.
Lower to a medium heat and wait for the liquid to evaporate a little (not to get completely dry!)
