Going meatless has never been easier with something as tasty as this Cauliflower Tinga. Tender pieces of cauliflower braised in a simple tomato-chipotle sauce can be served as a meatless filling for tacos, tostadas, burritos, or even enchiladas, but it also makes for a delicious side dish loaded with spicy flavor. For a quick and easy meatless meal, serve it atop warm corn tortillas and garnish with pickled onions and chopped cilantro.
