Preheat oven or grill to 350-375F
Slice the bread horizontally
In a food processor, or blender, combine all ingredients and pulse a few seconds until everything is combined
Generously spread the mixture on the bread, and set on a baking sheet with garlicky side up (if desired, sprinkle a little more cheese on top)
Bake or grill about 10 mins, until the mixture has melted and the edges are lightly toasted
If desired, broil a few minutes on high to toast a little more - optional
Remove from the oven, cut and serve
