Add all of the ingredients to a high speed blender and blend until creamy and smooth. Taste and adjust for flavor.
To heat and thicken the sauce, pour into a large, rimmed pan and heat slowly over medium heat. Whisk regularly until sauce is hot and thick - about 5 minutes.
For the pasta dish:
Prepare pasta as directed on the box.
Once pasta is cooked, add pasta and 2 cups chopped fresh spinach to the sauce. Cover for 2 minutes or until spinach is wilted.
Serve with an extra sprinkle of nutritional yeast, a dash of smoked paprika and a handful of toasted pumpkin seeds.
Notes
* The liquid smoke is optional. If you can't find it in the store, just add an extra tsp of smoked paprika!
