This is delicious, easy to prepare, and great for company. Put it into the oven before your guests arrive and have the water and spinach ready to go. It comes together quick and easy. I have always used the skin on thighs and tossed the linguine with all pan juices. For a lower fat version; you could substitute skinless chicken thighs and/or remove a some of the pan drippings before adding the spinach and pasta (keep in mind that is where all the flavor is and is the sauce for the pasta). Spaghetti or whole-wheat pasta may also be substituted.
