1. Thaw hash browns and remove moisture by pressing between paper towels. Preheat oven to 425 degrees. Coat nine inch pie pan with cooking spray. Press hash browns into pan, forming a crust. Brush with melted butter and bake for 25 minutes.
2. Remove crust from oven; reduce heat to 350 degrees, and sprinkle chives, cheese and ham into shell.
3. Mix eggs, half & half, salt and pepper, and pour evenly into shell.
4. Bake at 350 degrees for about 35 minutes, or until a fork inserted into quiche comes out clean.
