Add another tablespoon of oil to the pan, add the cauliflower florets in a single layer, sprinkle with the fajita spice and cook for about 3 minutes, until the underside is golden. Flip the florets, sprinkle with more of the fajita spice and cook for another 3 minutes or until the other side is golden. Pour the juice of ½-1 lime over florets and cook until it evaporates, stirring. Remove the cauliflower from the pan and set it aside.
Add the mushrooms in a single layer, sprinkle with the fajita spice and let them cook for about 3 minutes, until the underside is golden. Flip the mushroom slices, sprinkle with more of the fajita spice and cook for another 3 minutes, or until the other side is golden as well. Pour the juice of ½-1 lime over the mushrooms and stir around until evaporates. Stir the onion-pepper mixture into the mushrooms and turn off the heat.
Warm the tortillas, if desired, and keep them wrapped in a kitchen towel. To serve, place a few pieces of the cauliflower in the middle of the tortilla, followed by a small handful of the pepper and mushroom mixture and some chickpeas. Top with avocado slices, cilantro leaves and sour-cream, if using. Repeat with the other tortillas, as you go, and enjoy.
