To begin, bring two medium-sized saucepans of water to the boil.
Drop in the potatoes and cauliflower into one saucepan. Pour the dry pasta into the other saucepan and cook according to packet instructions.
Boil the vegetables for 8-10 minutes, or until soft. Drain and tip back into the saucepan. Add in the nutritional yeast, onion granules, garlic powder, vegetable oil, lemon juice, vegetable stock, salt & pepper.
Using a stick blender or food processor, blend the sauce ingredients until completely smooth. If your sauce is too thick, add another 50ml water and blend again. You want a creamy, rich sauce.
Add the pasta to your sauce and stir together well. Add in any other vegetables you like, such as sweetcorn or spinach.
Pour the Mac N Cheese into an oven-proof dish. Top with gluten-free rice crumbs and fresh herbs, such as parsley, if using.
If you’ve opted for the rice crumbs, place in the oven for 15 minutes at 220°C/425°F.
To serve, top with vegan cheese and fresh herbs to taste. Enjoy!
