In the meantime, cook the pasta in a large pot in salted, boiling water. Stir occasionally. For boiling time: follow the pasta package instructions minus 1 minute
When the pasta is ready, save 1 cup of pasta water, then drain pasta and mix it into the vegetables
Add some of leftover pasta water to the dish while stirring to make the pasta extra creamy. Keep cooking on medium heat for about 1 minutes
Sprinkle with fresh parsley and a drizzle of olive oil (optional) on top before serving, or add some of our fake parmesan cheese or some nutritional yeast.
