I am not sure what his original recipe was that he used, but this is what I have come up with and use in my own kitchen. This is perfect for a nice Saturday morning breakfast, and you can always garnish is however you wish. Amazing! Also this is a nice recipe for kids to make on their own if they want to make a nice breakfast for Mother's or Father's Day, or any such occasion, or just make it for yourself and indulge!
