Take 3/4th water (appx 1 ltr) in a large sauce pan or cooking bowl.
Bring it to a boil. Add 1 tbsp salt.
Now add the pasta to the boiling water.
Again bring it to a boil and cook until the pasta is cooked al dente.
This will take around 5 - 8 minutes depending on what pasta you are cooking.
Once done remove from the water by passing through a sieve or colander.
Make the pasta sauce
Heat olive oil in a pan or skillet.
Now add minced garlic and chopped or sliced onion to the pan. S
Saute till translucent.
Here you can add any vegetable of choice too. The most popular ones are mushrooms, broccoli, spinach leaves.
Then add a tbsp flour to the pan and stir nicely.
Now pour any plant-based milk slowly and keep stirring to avoid making any lumps in the sauce.
Now bring the mixture to a simmer.
Add the seasonings, nutritional yeast to the prepared sauce.
Simmer till you reach a desired creamy consistency.
Mix the pasta and sauce
Add the cooked pasta to the sauce and mix them all gently.
Simmer for another minute and turn off heat.
Add some more chopped fresh parsley leaves to the pasta.
You can also add some chili flakes to the pasta.
You can add more milk and a little more flour to make more sauce to the pasta. I have just enough of the sauce to coat the pasta nicely since I don't like more sauce in our pasta. You can add more as per the taste.
