The famous falafel burger from the all-vegetarian Harrison Street Coffee Shop! One of you vegancooking members needs to figure out how to make this and post a recipe. :) You would be performing a great service.
It's basically just a really big, flat falafel on a bun with tahini sauce, baby greens, and tomato. It comes with sprouts, too, but I'm not a fan. The photo makes it look overdone, but it was actually just about right - crispy around the edges.
The burger comes with chips or salad, but if you ask for vegan coleslaw, they will indulge you for a few extra cents. :)
