The chicken bakes together in your skillet with cubed feta, cherry tomatoes, whole kalamata olives, red peppers, onions, serrano chiles, and garlic. After baking for 20 minutes the feta melts and the vegetables will be soft and you can mash them together easily to create this easy sauce-in-a-pan. This sauce then serves to coat the pasta. However, I suppose if you don't want to mash them and want to keep them as soft-but-intact, that's fine too. Although note that the pasta won't have much sauce to be coated with and you may want to drizzle additional olive oil over the finished dish.
