Cut a 2 1/2" to 3" circle off the top of the bread, remove and set aside. Reserve the circle for dunking in the chili, if desired. Hollow out the loaf, leaving a 1/2" or so of bread around the inside of the bread, creating a bowl. Place the bread bowl on a plate. Heat the chili in a medium saucepan. When hot pour into the bread bowl. Scoop out to serve and top with tofu sour cream and guacamole.
