Break the noodles into small bite-sized pieces and cook according to the package directions. Drain and set aside until ready to use.
In a large pot over medium-high heat, cook the onion in the oil for about 5 minutes, or until it begins to brown and becomes fragrant. Add the mushrooms and garlic, and cook for about 5 more minutes, or until the mushrooms begin to brown.
Add the tomato paste, oregano, and sea salt and cook for 1 or 2 more minutes, or until the paste begins to darken.
Add the vegetable stock and crushed tomatoes. Bring to a boil and then reduce the heat and let simmer for about 10 minutes, or until the liquid reduces slightly.
Stir in the noodles and basil and simmer for 2 or 3 more minutes.
Remove from heat and divide the soup among four bowls. Top with the Walnut Parmesan and Cashew Ricotta, if using.
