I’m not a big fast food person, but when I moved to California I would go to In N Out every chance I could! I took every opportunity (within my tight grad student budget) to save up and splurge on a really good quality burger & fries… and I always loved the sweet and tangy sauce.

So, naturally, I had to make my own vegan In N Out sauce for BBQ veggie burgers and crispy oven baked fries. When I moved from California to the east coast a few years back I really missed my In N Out, so this is my attempt on bringing a little bit of Cali to New England.
