Get all your ingredients ready.
In a casserole add the cauliflower, plant-milk, garlic, spices, and cashews.
Boil all the ingredients on low heat until the cauliflower is completely soft.
Pour everything in a high-speed blender and add nutritional yeast. If you need to add more liquid it's ok to add a little bit of plant-milk. Add 1 tbsp of lemon juice.
Boil the pasta as per instructions on the box. Drain the pasta and pour the sauce over. Give it a good mix, and plate up. We love to add pepper, chili flakes and vegan parmesan cheese on top.
