Heat the olive oil in a medium saute pan over low heat. Add the garlic and herb mixture and cook for 3 minutes, until the garlic is tender but now browned. Remove from the heat and set aside.
Cut the ciabatta in half horizontally, running a serrated knife parallel to the board. Spoon the garlic mixture onto the bottom half and spread the butter on the top half and place together.
