Heat oven to 450°F. Cut the cauliflower into small florets and toss with the oil, chipotle, cumin and salt.
Roast on a sheet pan 20-25 minutes until browned at the edges. Add the drained black beans to the pan for the last 5 minutes.
Stir the slaw mix with the vegan mayo, juice of 1 lime and a pinch of salt.
Warm the tortillas and fill with cauliflower and beans, then top with slaw and cilantro.
Serve with lime wedges. For mild palates, skip the chipotle and use regular chili powder.
