This has to be one of the most amazing chicken dishes I have ever made or eaten. It's really scary to watch people just attack this dish and practically inhale it in one breath. Brush up on your Heimlich Maneuver, people do get a little over-enthusiastic over this. Prep time includes marinating time.
This is old-fashioned, from scratch, comfort food. This has been a family favorite for years. I like to take this to other families when they are in need of a meal. It's always a winner. I like making it with leftover turkey, too! I often add some cooked diced potatoes.
I don't know where this recipe originated, but it has been an old stand by on my mom's dinner party tables for years. It actually bakes up to look quite impressive. Please don't try to substitute fresh mashed potatoes (believe me I have tried) the instant box stuff provides the perfect texture.
