Italian Cheesy Bread

As promised, one more recipe from Italy. The second night I was there, we sat down for a dinner with a few member's of Daniele's family. Daniele's mom prepared some excellent cheesy bread for us all to share.

Carve out the inside of the Italian bread. Also, slice the red onion and cheeses. Mix in a bowl the red onion, cheeses, and some mayonnaise. Insert into the center of the bread, place the top of the loaf back on the bread, wrap in foil, and bake in the oven. Serve hot with crackers and pieces of the inside of the loaf of bread.
