Step 1

Cook pasta in salted water according to package directions until al dente.

Step 2

While the pasta is cooking, in a bowl of a food processor, pulse the tomatoes and their oil until finely chopped. Add garlic, basil, and red pepper flakes. Season with salt and pepper to taste. Pulse until the mixture resembles paste like consistency. It will be thick and you may have to stop the food processor to scrape down the sides.

Step 3

Drain the pasta, reserving 1 cup of the cooking water. Return the pasta to the heat and stir in the spinach, sun-dried tomato pesto, and reserved cooking water. Stir until the spinach has wilted. Then add the Parmesan cheese. Taste for salt and pepper.

Step 4

Serve with sprinkle of chopped basil and more Parmesan, if desired.
