This all-plant sheet-pan fajita spread made with tofu is the ultimate in easy dishes to serve a crowd. It requires minimal prep time and minimal kitchen tools, which also makes for minimal (a.k.a. quick) cleanup. Be sure to serve it with an array of different accompaniments. Good ideas include corn tortillas, refried beans, mashed avocado, diced tomato, salsa, cilantro, and sour cream.
