Falafel, a nice gluten free, veggie option.
Most towns now have a kebab shop where you will easily find Falafel, but they are often coated in breadcrumbs which is ok for vegetarians, but not if you are gluten intolerant or Celiac. No worries, easy enough to make at home and I suggest you make a whole batch and freeze in lunch size portions for lunch another day.
