Preheat your oven to 180 degrees C, 160 fan, gas mark 4.

Take your head of cauliflower, chop it into bit size florets, and place it in a mixing bowl.

Add in the olive oil, cumin, paprika, garlic powder, and salt and pepper. Give it a very good mix up, and ensure that everything is evenly coated. I like to use my hands for this, but a spoon should work just as well - but it may take a little longer.

Lightly oil a large baking tray, and tip the seasoned florets onto it. Make sure it's in a single layer and evenly distributed!

Roast! Place the tray into your preheated oven, and roast for 35-40 minutes. I found that 38 minutes was the sweet spot in my oven, but it all depends on how well you like it cooked.

Sprinkle over salt to taste, and put it into your serving bowl/plate. Drizzle with tahini and the chopped parsley if desired, and enjoy!
