The not-so-secret secret to the best barbacoa? Spices. Which is why this vegan version uses no less than six! Grilled and shredded eggplant and thinly sliced mushrooms are the perfect stand-in for traditional lamb or beef. Enjoy in corn tortillas with lime wedges, diced tomato, pickled onions, cilantro, sliced jalapenos, vegan cheese and vegan sour cream.
