Chances are you have all of the ingredients for this pasta dish on hand, in your refrigerator and cupboard. That’s how it came together in my kitchen, and what a felicitous combination of flavors it turned out to be. Plus it goes together in a half hour or less. Be sure to use a milder blue cheese so it doesn’t end up overwhelming the other flavors. You could substitute broccoli for the spinach, and you could leave out the chicken for a vegetarian dish (use vegetable broth instead of chicken). This goes well with a dry white or medium-bodied red wine.
