I’m vegetarian too, so initially I assumed I would only have the avocado option, but I think the Mexican Corn Chilaquiles and Eggs Bowl might also be vegetarian. I’m definitely going to ask.
They say that pastries will be available for everyone, and maybe that will include the doughnuts too. Alternatively, it looks like the avocado thing (which looks revolting in the photo, IMO) comes with salad, so maybe you could that they substitute the doughnuts. It’s worth a shot.
I agree with you that I’m surprised they aren’t feeding us from Andy’s Lunchbox. Though I don’t think they have brilliant vegetarian options either (esp if they can’t even make a chocolate pop tart without adding bacon to it - I’m still bitter about that!).
