Preheat oven to 375 degrees. Spray a 9-inch pie pan with non-stick cooking spray.

Place hash browns in pan and drizzle with melted butter. Bake for 20 minutes.

In a bowl combine eggs, milk and seasoning salt and whisk thoroughly. Set aside.

On top of cooked hash browns, evenly layer cheddar cheese, Swiss cheese and finally the ham. Pour egg mixture over the top.

Bake at 350 degrees for 40 minutes or until eggs are set. Remove from oven and let sit for 3 to 5 minutes. Serve warm.
