I've packet mine. But easier would be mixing everything and add to baking dish. As you can see I layered mine with Bacon then grated potatoes and then thinly slices of chicken, and repeated the steps twice.

Mix your chicken a la king sauce and yogurt, add salt and pepper to taste. Pour over your mix.

Add cheese and bake for 45min at 120 degrees. Before dishing check that all is covered in sauce and cheese.
