1/4 C parmesan cheese
Preheat oven to 350 degrees and spray a 9×13 casserole dish with nonstick spray. Layer the chicken in the bottom of the dish followed by the ham and finally the swiss cheese.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute. Slowly add the milk, whisking to keep clumps from forming.

In a small bowl, mix together the topping ingredients until the butter is evenly distributed over the crumbs. Sprinkle over the top of the dish and bake for 45 minutes. Allow cooling for 10 minutes before serving so the sauce with thickening just a bit.
