Well they've always said that they'll start stocking Gluten Free sandwiches when a suitable bread came onto the market and they've come through on their promise.
Starbucks "NEW! Wheat and Gluten Free Tuna Sandwich
Pole and line-caught Skipjack tuna with roasted tomatoes and basil mayo, topped with rocket leaves served on Genius gluten free™ bread."
I just walked about a mile to my nearest Starbucks on my lunchbreak. Couldn't see them, asked the lady behind the counter, explained in lots more detail what I meant while being met with a dumb expression, then finally when the penny dropped was told "oh, the tuna ones? Oh, we only get one or 2 of those and they go in the morning."
Hope they remain a success and I get a chance to buy some. It'll be a real treat to be able to buy sandwiches when I'm out and about. I might even stop carrying around emergency food rations wherever I go!
