  3. While pasta is cooking, place vegan butter in large non-stick pan. Once melted, add sliced/chopped leeks and mushrooms. Cook until soft, then add garlic. Saute for 45-60 seconds, then add 1 cup of water.
  4. Simmer vegetables for 10-12 minutes with top off.
  5. Dissolve arrowroot powder in 3 Tablespoons of cold water and mix thoroughly. Set aside.
  6. After vegetables have simmered for 10 minutes or so, add remaining spices, seasoning paste, plant milk, nutritional yeast, and arrowroot mixture.
  7. Simmer another 5-8 minutes until mixture reaches desired thickness.
  8. Serve immediately over pasta. Top with basil ribbons and vegan parmesan cheeze if desired.
