Pickler has great gluten free bread and will ask if you are allergic/celiac. The sandwich is wrapped in foil before grilling to avoid cross-contamination and the staff member handling it will usually change gloves. Not for the severely allergic as they do not always change gloves. Tell them to change gloves and keep an eye on who’s handling that sandwich.
They're low gluten, like gf bread and stuff, they're not actually gluten free.
The best GF egg sandwiches I've ever had this side of the Mason-Dixon.
