Eating gluten-free during a road trip in mainland Greece

We recently returned from a wonderful family vacation in mainland Greece. Because we were road tripping and traveling to remote areas well outside of Athens, I translated into Greek my dietary needs and provided this translation to restaurant staff when necessary. This was very helpful as I sometimes found that even in restaurants that advertised gluten-free options online, the waitstaff didn’t always know what I meant by “gluten”. What I ate: Stuffed Grape Leaves The dolmas (grape leaves stuffed with rice, meat,...

Long story short: Wheat bread was tested for gluten using the LEO tester. After 3 minutes, there was a faint line above the E as confirmed by the LEO app. According to the LEO website, “If you see a line above the "E" of LEO then the sample is 10 PPM or less.” Hmm. Long story long: Over a two day period (that included a lot of thinking and a phone chat with Adrian Rogers, a specialist in immunoassay development...
