The heat of chile, spices of North Africa and earthiness of kale beautifully complement sweet butternut squash in this hearty ragout. Bright, rich and healthy, this recipe is easily prepared in 30 minutes making it a delicious option for a weeknight. If you prefer an even richer stew, hot Italian sausage may be added. Most likely, however, you will find that the meatless version is substantial and satisfying enough to win over any carnivore. Use vegetable broth if you wish to keep it vegetarian. Be sure to serve the ragout with couscous to soak up the liquid.
