Creamy Vegan Cauliflower Cashew Alfredo

0 Fill a medium saucepan half full with water and place on stove over high heat. Add cauliflower, cashews, garlic, and onion. Boil for 10 minutes until cauliflower is VERY soft - should crumble easily when pierced with a fork.
1 Drain water and transfer the cauliflower, cashews, garlic and onion to a high speed blender. Meanwhile, fill the same medium sauce pan with water and cook pasta according to package instructions while you finish making sauce.
3 Drain cooked pasta, reserving 2/3 cup of pasta water and set aside. Return the cooked pasta to the pan.
2 Add the remaining ingredients along with 1/2 cup of pasta water to the blender and blend on high until super smooth and creamy. Add more water if needed. Season to taste.
4 Pour blended Alfredo sauce over the noodles and stir to coat, adding pasta water little by little if needed.
5 Sprinkle with parsley and serve hot, topped with fresh cracked black pepper, reserving a little extra parsley for a finishing garnish.
