Preheat the oven to 200 C.
Cut up your cauliflower into small, bite size pieces and stuck them in a bowl.
Throw in your olive oil, chillis, garlic salt, almond flour and salt and pepper and shake everything about. You could also do this in a big ziplock bag. Whatever works.
Spread the cauliflower in a roasting pan in a single layer and roast for about 25 minutes in the hot oven.
