In a large bowl, combine the coconut milk, brown sugar, soy sauce, garlic, cumin, orange zest, and salt and pepper, to taste. Pour half of the marinade into a large resealable bag. Reserve 2 tablespoons of the remaining half of the marinade for the Online Round 2 recipe Sweet and Spicy Chicken Wraps. Reserve the rest of the marinade, for the dipping sauce, in a small bowl. Cut each chicken thigh into 6 strips and add to the bag with the marinade. Put the bag into a bowl, in case of leakage, and refrigerate for at least 1 hour or overnight.
Meanwhile, if you are using wooden skewers, soak them in water for at least 30 minutes.
Dipping sauce, whisk the peanut butter and hot sauce into the reserved dipping sauce marinade. Cover and refrigerate until ready to serve.
Preheat a grill or grill pan over medium heat. Remove the chicken from the marinade and discard the marinade. Thread 4 pieces of chicken onto each skewer. Put them onto an oiled grill and cook until slightly charred and cooked through. Reserve 4 skewers for the Online Round 2 recipe Sweet and Spicy Chicken Wraps.
Preheat a grill or grill pan over medium high heat. Make the couscous according to package directions and set aside.
Cut the pepper into quarters and remove the core and the seeds. Slice the zucchini and onion into 1/4-inch thick slices. Season the vegetables with salt and pepper, to taste. Grill the vegetables until they are slightly charred and have softened a bit, about 2 to 3 minutes per side. Remove them from the grill and cut them into small pieces. Gently stir the chopped vegetables into the couscous, cover, and keep warm. Reserve 1 cup for the Online Round 2 recipe Sweet and Spicy Chicken Wraps.
Arrange the skewers on a serving platter and serve with the dipping sauce and the couscous.
