Preheat the oven 200 and line a baking tray with parchment paper.
Cut the leaves of and then cut cauliflower in small florets and add to a large bowl. Add the yoghurt, cumin, salt and smoked paprika. Give everything a good stir until the cauliflower is covered.
Then add the panko and tussle the florets to cover. Dump everything on the baking tray and put in the oven for about 25 minutes. Flip once halfway through the baking time.
Meanwhile, slice the avocado. Then, make the sauce by mixing the ingredients together - if you don't like heat, leave the hotsauce out.
Take the cauliflower out of the oven. Heat the tortillas in the microwave for about 20 seconds. Then, make the tacos by adding the cauliflower, avocado, pickled onions and chili sauce. Enjoy!
