Pre-heat your oven to 200C / 390F. Slice the cauliflower into large quarters, no need to remove the leaves or core (reduces food waste and it adds texture and flavour). Place the cauliflower into boiling water and simmer for 5 minutes
Meanwhile soak the 50g cashews in hot water for 5 minutes. Drain the cashews, add to a blender cup along with 200ml almond milk, 4 tbsp nutritional yeast, 1 tbsp olive oil, 1 tsp dijon mustard, salt and pepper and blend until smooth
Drain the cauliflower and place into a baking dish or skillet pan and pour over the cheesy sauce
Place in the oven for 15-20 minutes at 200C / 390F or until golden
