Jimmy Johns is great they offer the sandwiches as lettuce wraps and they have great options. My fiancé with a gluten intolerance loves their tuna salad sandwich as an unwich, he hasn’t had a problem with it. If you have celiacs then I would probably question the staff about their cross contamination precautions.
