What are sweet potatoes doing in a fajita, you ask? Everything, we say! These tasty tubers are the perfect way to make Tex-Mex night meatless. After cutting them into thick wedges, we give them a dusting of warm spices and roast them in the oven until they’re tender as can be. And with the help of some seriously satisfying toppings—pickled jalapeño, sautéed onion and green pepper, tomato salsa, and lime sour cream—this recipe packs everything you could want inside the fold of a tortilla.
