Cook vegetables: Bring two pots of water to a boil. Add the chopped vegetables and the garlic cloves one pot and cook them for about 10 minutes or until they are soft. Keep about ½ cup of the cooking water and drain the rest.
Cook the macaroni in the other pot. Drain well.
Blend the cashews, cauliflower and potatoes, coconut milk, nutritional yeast, lemon juice, garlic powder, paprika, salt, and pepper until really smooth and creamy. Add some of the reserved cooking water little by little to reach the right consistency.
Adjust the taste again and serve immediately.
Notes
Pasta: You can use any pasta shape you like.
Cauliflower: Fresh or frozen. If frozen, you can cook it from frozen; there’s no need to defrost it.
Coconut milk: Preferably full-fat (creamier & tastier), but low-fat works too.
Nutritional yeast: Not baker's yeast; they are two completely different products.
