For a smoother hummus, remove the skins from the garbanzo beans before processing. Adjust the amount of Buffalo wing sauce to your preferred level of spiciness. If you don't have fat-free ranch dressing, you can substitute plain Greek yogurt for a tangier flavor. This hummus can be made ahead of time and stored in the refrigerator for up to 3 days. Bring to room temperature before serving. Experiment with different types of pretzel crisps or pita chips for dipping. Try adding a squeeze of fresh lemon juice for extra brightness.
