We are going to be in Greece for 16 days. Traveling on the mainland for a week and then to Santorini, Crete and Rhodes. I was wondering how hard it is to find vegetarian food in the smaller towns and islands. Also my husband is deathly allergic to chickpeas and what the best way to convey that is to the waiter. We are very excited about this trip, I hope this won't interfere with our good time.
