Preheat the oven to 450° F. Cover a baking tray with parchment paper.
Cut the cauliflower into bite-sized florets.
In a bowl, combine the milk, water, flour, yeast and spices. Mix until you get a smooth texture. If too runny, add a little more flour. If too thick, add a little more milk.
Dip the cauliflower florets in the flour mixture. Mix gently to coat.
Place on a baking sheet and place in the oven for 20 minutes until golden.
While the cauliflower cooks, prepare the sauce by combining the hot sauce, tahini and maple syrup in a large bowl.
Once golden brown, remove the cooked cauliflower from the oven and place into the bowl with the hot sauce. Mix gently to coat.
Put the wings back on the baking sheet and cook for another 10 minutes. Cool.
Lay out wraps. Assemble the wraps by layering the lettuce, avocado, onion, cauliflower and vegan sour cream. Wrap and serve immediately.
