Cook your pasta according to package directions, reserving 1/4 a cup of pasta water before draining.
In a pan over medium heat, saute the diced onion and garlic until translucent, approximately 3 minutes. Then add in the tomato paste, vodka, almond and coconut milk and 1/2 of the red pepper flakes.
Pour in the reserved pasta water and cooked penne to the pan. Stir until the pasta is coated, adding a handful of spinach in at the end. Serve with nutritional yeast and more salt and pepper as desired.
