Update 5:
Started the new year trying some more offerings from Chef Avila. Also, looks like Guerilla Tacos is traveling to more places (new locations below).
Roasted Cauliflower Taco (Chile Morita, Castlevaltrano Olives, Medjool Dates, Parsley, Cashews):
Really a fantastic taco, with a nice balance of flavors. Loved the spicy & savory of the Chile Morita salsa with the Cauliflower and Medjool Dates).
Wild Mushroom and Pork Torta (Hedgehog, Black Trumpet, and Yellow Foot
Mushrooms with Roasted Pork Shoulder, Habanero Chile, Herbs):
It’s silly to think what Chef Avila is capable of cooking and creating inside of a tiny food truck. The Pulled Pork is really tender, juicy, not overly salty, and the trio of mushrooms… so good!
