On a grill over low heat, grill the cube roll, salting both sides of the meat.
Separately, prepare the mixed berries in a saucepan over medium heat, softening the berries and obtaining a smooth sauce. Add sugar to taste and some red wine.
To serve with the meat, prepare some rustic potatoes and a Chilean tomato with onion salad.
Once the meat is done, serve together with the salad, pour the berry sauce over the meat, and enjoy!
