"I don't know if this has been posted before, but just a FYI about prepared sandwiches, wraps and salads, all kosher under the Star-K, available at Newark Airport: Not only at the JetBlue Terminal A by gate 16, but also at Market Fresh in Terminal C, in the Food Court area.. you walk by it on your way to the gate for United's flight to Israel. Not cheap, but actually very tasty. They had at least one gluten free offering, as well."
