Finding vegan food isn't hard if you know where to look! Check out this amazing pizza place I used to live around the corner from in D.C. called 'Timber'.
This is the first pizza spot I enjoyed in DC and it was walking distance from my home. It's a little gem in the Upshur neighborhood. You may also find their food truck floating around the city too. Here is my go to from their menu when I stop by:
The Vegan Bentley Vegan Nachos (my fav fav)
