Place pasta, tomatoes, sun dried tomatoes, onion, garlic, in a large stock pot. Pour in vegetable broth.
Sprinkle the pepper flakes and oregano on top.
Drizzle with olive oil if using
Add ½ tsp salt and some ground black pepper
Cover pot and bring to a boil. Reduce to a low simmer and cook for about 10 minutes, stirring every 2 minutes. Cook until almost all the liquid has evaporated until there is about one inch of liquid left in the bottom of the pot. Add the fresh basil and serve.
