In a medium bowl mix all the ingredients well and set aside.
With a serrated knife cut the bread into slices without cutting all the way through the bottom. This is so that it can hold the butter mixture better.
Spread the butter mixture between the slices of bread. Wrap the loaf of bread with aluminum foil leaving the top uncovered and bake on a baking sheet for about 15-20 minutes or until it starts to turn golden brown on top and the cheese starts to melt. Serve immediately.
