Lidey's Chicken Chili with Butternut Squash and Moroccan Spices

Heat olive oil over medium heat in large heavy-bottomed pot or Dutch oven. Add onions and cook over medium heat for about 5 minutes, until translucent. Add butternut squash and garlic and cook for one more minute, until garlic is fragrant. Add tomatoes, chicken stock, cinnamon, paprika, cumin, allspice, harissa, brown sugar and 2 tsp. salt and bring to boil over medium heat. Reduce heat to low and simmer for 35 to 40 minutes, until squash is tender and broth has thickened considerably. Using a potato masher, bottom of a whisk or a wooden spoon, lightly mash about half of butternut squash. (Don’t worry about being exact here—the idea is just to thicken the broth while still leaving some whole chunks of squash.) Add chicken and chickpeas and simmer for 10 more minutes. Taste and add another 1/2 tsp. of harissa if desired. To serve: In small bowl, combine 1 cup yogurt with 1/4 tsp. salt and 1/4 tsp. freshly ground black pepper. Ladle chili into bowls and top with a spoonful of yogurt and a sprinkle of parsley. Serve hot.
