Socca is a crispy pancake made from chickpea flour (and or garbanzo flour). These flours are made from ground chickpeas.
Socca is generally gluten-free, but there are some recipes that call for gluten, so double check.
I first found out about Socca while I was in Nice, France last year. I must say going to France, not knowing the language and then trying to ask for gluten-free options was quite difficult. I was lucky to find a pizza parlor that only made GF Socca! How psyched was I? I may have put on a pound or two, but I was super excited to have found a spot where I did not have to worry.
