Cook pasta and vegetables: Bring two pots of water to a boil. Add the chopped vegetables and the garlic cloves to the smaller pot and cook 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 vegetables, coconut milk, nutritional yeast, lemon juice, garlic powder, paprika, salt, and pepper until really smooth and creamy (immersion blender or food processor). Add some of the reserved cooking water little by little to reach the right consistency.
