Starbucks sandwich

Does this sandwich exist in the UK or is it just a Berlin Starbucks thing?

My buddy Joe sent me the following photo of a tasty vegan sandwich now available in Starbucks across the German capital.

Check it out.

It doesn’t look groundbreaking but Joe assures me it was incredibly enjoyable. The seeded bun housed guacamole, cucumber, red peppers and lettuce.

Have you tried this vegan sandwich in Berlin? Have you seen it outside of Berlin?
