I love the efficiency of a one-pot meal. If you’re going to the trouble of boiling a pot of water for pasta, why not blanch some vegetables while you’re at it? Subtract a minute or so (depending on what is being added to the pot) from the pasta cooking time, and everything will be al dente and ready to be drained at the same time.
Spinach, Pine Nuts, and Radicchio Pasta
Bring a medium pot of water to a boil; season generously with salt. Cook pasta according to package directions. Add spinach during the last minute of cooking. Reserve some pasta water (a glass measuring cup works well), and drain pasta and spinach. Return everything to pot. Add pine nuts, parmesan, radicchio, lemon zest and juice. Add some reserved pasta water to desired consistency and drizzle with olive oil. Toss everything together and season with salt and red chile flakes.
