Preheat the oven to 375°F and grease a 9x13 inch baking dish.
In a large bowl, whisk the cream cheese, heavy cream, dijon mustard, lemon juice, garlic powder, onion powder, salt and pepper until smooth and creamy.
Fold the chicken, ham and shredded swiss cheese into the sauce until everything is evenly coated. Spread the mixture into the baking dish.
Lay the swiss cheese slices over the top so they cover the surface.
In a small bowl, mix the crushed pork rinds, parmesan, melted butter and parsley until it looks like coarse buttery crumbs. Sprinkle evenly over the swiss slices.
Bake for 25 minutes until the filling is bubbling around the edges and the topping is golden and crisp. Let it rest for 5 minutes before serving.
