Chop the cauliflower and toss with olive oil, garlic powder, smoked paprika, salt, and pepper.
Air fry the cauliflower at 380°F for 15 minutes, shaking every 4 minutes.
In a blender, combine the sour cream, 1-2 chipotle peppers in adobo sauce, lime juice, salt, and pepper. Blend until smooth.
In a bowl, layer the rice, roasted cauliflower, sour cream sauce, black beans, shredded cabbage, guacamole, pico de gallo, and fresh cilantro.
Serve with hot sauce, if desired.
