Chickpeas and garbanzo beans are the exact same thing! Chickpea just comes from the French “pois chiches” and garbanzo bean from the Basque “garbantzu."
Soup makes an easy meal. Heat some onions, carrots, celery, and garlic. Add herbs and spices. Simmer in liquid for 30 minutes. Finish with lemon juice or vinegar.

Well, mostly because this garbanzo bean soup isn't classic. Traditionally, pasta e ceci uses ditalini, but any small pasta will work.
Pasta e ceci is traditionally finished off with grated Parmesan or Pecorino Romano. You can, of course, omit it if you are vegan or a vegetarian who avoids rennet..
