Throw it all in the pot, INCLUDING the uncooked Pasta, and cook! - Bring it to a boil, thenreduce to a simmer. The starch leaches out of the pasta and makes a rich, warm sauce for the noodles. The other ingredients cook right along with the pasta
Place pasta, tomatoes, onion, garlic, basil, in a large stock pot. Pour in vegetable broth. Sprinkle on top the pepper flakes and oregano. Drizzle top with oil.
Cover pot and bring to a boil. Reduce to a low simmer and keep covered and cook for about 10 minutes, stirring every 2 minutes or so. Cook until almost all liquid has evaporated - I left about an inch of liquid in the bottom of the pot - but you can reduce as desired .
Season to taste with salt and pepper , stirring pasta several times to distribute the liquid in the bottom of the pot. Serve garnished with Parmesan cheese.
