So so good.
Best with a cast iron skillet, like this beauty: Le Creuset Cherry Cast Iron Skillet.
Brown/pan fry the potatoes in oil with a lid until they're mostly cooked through. Onions, garlic, seasoning (Tony's, of course), and for this one sliced ham and fresh mozzarella cubes. Whisk eggs (7! for this 12 inch skillet, and I think five potatoes) with a little water, mix it all together, then bake at 400 until brown and set.
So so good. I ate so much of it.
