Cut the top portion of the bread and remove the center of the bread, making sure not to damage the crust or walls, since it will serve as a container.
Mix the cheeses, minced scallion, wine, pepper, and blueberries in a bowl.
Stuff the bread with the cheese mixture and put in the oven with top and bottom heat at 400°F. Wait for 10 to 15 minutes, depending on the oven, until the bread is a bit brown (it is important that it is crunchy), the cheese has melted, and the surface starts to brown as well. If necessary, finish under the grill 5 minutes to brown the surface a bit more.
Serve together with bread, crackers, breadsticks, or any other ingredient to taste. Once you are out of stuffing, split the bread filled with cheese with your hands.
