Mix together the dough ingredients and knead for 5 minutes to form a smooth dough. Pop into a bowl, cover with clingfilm and set to one side to rest to 30 minutes.
Put the cauliflower in one bowl and the onions and peppers in a separate bowl. Mix together the spice ingredients and add 2 tbsp to the cauliflower bowl and 1 tbsp to the onions and peppers, tossing both with 2 tbsp of olive oil.
Separate the dough into 80-85g pieces and roll into rough circles. Working one at a time, cook the wraps in Roccbox for between 20 and 30 seconds, rotating halfway through. Pile the wraps up on a plate and cover with a clean tea towel until required.
Heat a cast iron pan in Roccbox and add the cauliflower. Cook for 2-3 minutes, then add the onions and peppers and cook for a further 1-2 minutes.
Squeeze the remaining lime juice into the remaining coconut milk and pop into a separate serving bowl. Serve everything at the table with a few sliced chillis and let everyone get stuck in building their fajitas!
