In a large mixing bowl, combine ground chicken, egg, plain bread crumbs, minced onion, garlic powder, dried parsley, salt, and ground black pepper.

Grease a loaf pan or line it with parchment paper. Spread half of the chicken mixture evenly in the bottom of the loaf pan. Lay 3 slices of Virginia chicken ham over the chicken mixture. Place 3 slices of Swiss cheese on top of the ham. Repeat the layering with the remaining chicken mixture, ham, and cheese.

Place the loaf pan in the preheated oven and bake for 25 minutes. After 25 minutes, remove the meatloaf from the oven and sprinkle panko breadcrumbs over the top. Return the meatloaf to the oven and bake for an additional 15 minutes, or until the internal temperature reaches 165°F (74°C).

While the meatloaf is baking, melt butter in a medium saucepan over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux. Gradually add heavy cream and milk, whisking continuously to avoid lumps. Stir in Worcestershire sauce and Dijon mustard. Bring the mixture to a simmer and cook until thickened, about 5 minutes. Remove from heat and stir in grated Parmesan cheese, freshly grated nutmeg, and salt and pepper to taste.
