Remove the roasted red peppers from the jar and discard the liquid. Chop half of the roasted peppers into small pieces, and reserve the rest for the sauce.
At this point, add the pasta and broth. Cover the pot with a lid and cook for about 12-14 minutes, until the pasta is al dente and almost no liquid remains.
In the meantime, make the sauce. Place the remaining roasted peppers, coconut milk, and nutritional yeast into a blender, or a smoothie cup, and process until smooth.
Add the sauce to the pasta. Then add the fresh basil and spinach and cook, stirring often, for about 2 minutes, just until the spinach has wilted and the sauce is heated through. Serve.
