In a blender or food processor, add the garbanzo beans and puree. Combine the olive oil, lemon juice, garlic, pepper, paprika, tahini and parsley. Blend well. Add the reserved liquid, on tablespoon at a time, until the mixture has the consistency of a thick spread. Serve immediately or cover and refrigerate until ready to serve. Serve with raw veggies, such as broccoli and carrot sticks.
