Turn the oven to gas Mark 5
Place the cauliflower florets on a baking tray and coat with the olive oil and salt & pepper. Place in the oven and roast for 40 minutes to 1 hr. Turn twice during this time so that both sides of the cauliflower are nice a charred.
Add the quinoa, water and boulion to a saucepan, stir thoroughly and bring to the boil. Simmer for 20 minutes, adding more water as you go along if it’s looking too dry. (I like to cook the quinoa for longer than is recommended on the instructions as I like the grains to really open out and become fluffy).
When the quinoa is cooked, take off the heat and pop it into a larger bowl, then stir in the nutritional yeast and mustard.
Next make the tahini dressing. Add all the ingredients to a mini chopper and blitz. (If you don’t have a mini chopper, you can smash up the garlic, salt & pepper in a pestle and mortar and the mix all the ingredients thoroughly in a small bowl).
When the cauliflower is nice and roasted, remove from the oven and add to the quinoa. Add the rocket and crushed hazelnuts to the mix and gently stir everything together.
Divide in to two bowls and drizzle with the tahini dressing.
