Traditionally, tacos al pastor are made from thin slices of marinated pork and pineapple that roast on a rotating spit and then are shaved off into thin slices. But now, you can experience a cauliflower version of this Mexico City favorite right in your kitchen. Fragrant orange zest, smoky chipotle chiles, garlic, and honey make up the flavorful marinade that coats the cauliflower florets, while annatto, a paste made from achiote seed, give them their vibrant color. Tossed and roasted alongside pineapple and onion, it's a major hit. A zesty avocado salsa drizzled on top brings just the right amount of brightness to these crave-worthy cauliflower tacos.
