Preheat oven to 350 degrees. In a medium sized bowl combine the cream cheese, sour cream, salsa, and cheese.
Cut the top off of the loaf and hollow out the loaf leaving a hole in the bread. Cut the remaining bread into cubes.
Scoop the dip into the bread bowl. Using the Reynolds Wrap® foil the bread and seal. Place on a baking sheet and bake for 25-30 minutes or until heated throughout. Place the remaining bread cubes on the baking sheet the last 10 minutes of cooking.
