Dear Migros
First of all, I think it's great that you're offering more and more vegan food.
Unfortunately, however, there is still no sandwich that is purely plant-based. During my internet search, I saw that this wish was already expressed here in the forum in both 2013 and 2014, and now it's already 2017... It would be really cool if you could buy a sandwich in Migros for the journey.
For example, the Anna's Best Vegi SW Cucumber & Tomato simply with a vegan cream cheese. Or with hummus and grilled vegetables. There are so many possibilities!
Thank you for the consideration and have a great day!
Best regards
Anna
