Candocook, just some wee bit more information. Falafel is actually a sandwich which is filled with fried fritters (traditionally made of dry fava beans and in some places with chickpeas) along with some type of dressing (Hummus) and fillings (your choice, you can be creative, it may not be traditional but hey it has to suit your taste buds right).
A lot of Indian and Middle eastern fritters use raw beans (soak them overnight and then drain the water and grind it add some salt, seasonings and fresh herbs and even a finely chopped jalapeno to it and you are ready to fry them).
In Indian cooking we call that vadas. They can be made with Moong beans, Urad or white beans and any other beans you can think of.
In case of hummus yes skinned garbanzo would be great but it's too much work even after soaking them overnight so I skip it. Just another tip that I have learned is that if you make your chickpeas at home (don't buy the canned stuff) and soak them overnight a lot of the skin will come off of them that you can rinse off and pick out. Although to get it perfectly skinned (all of them is a stretch for me - LOL
