In a large mixing bowl, whisk together eggs and milk. Add in chopped ham, feta, onion, potato, black pepper and garlic powder. Mix together well.
Pour mixture into a greased 13x9 glass baking dish.
Bake uncovered for 30-40 minutes, or until egg is cooked through in the center.
Let cool and slice into squares. Refrigerate up to 3 days, freeze remainder if you will not eat within that time. (food safety, people!)
