When I was growing up, it was always a special treat to have a can of corned beef hash for breakfast. This is the same idea, but much better than whipping out the can opener and serving up a bowl of Mary Kitchen! If you're not a spicy pepper person, use a bell pepper instead, but I like adding pickled cherry peppers to my hash--just thinking about them makes my mouth water. Then toss in some fried onions and potatoes, and you'll have a dish that pretty much scratches any and all brunch itches. Salty, sweet, greasy, and spicy . . . mmmmm!!!
Put the diced potatoes in a medium saucepan and fill with water to cover by an inch. Season with salt and TASTE the water--it should taste salty like the ocean. Bring the water to a boil over high heat and cook the potatoes until JUST cooked through, about 8 minutes. Drain the potatoes, spread them out on a baking sheet and let them cool completely. HINT, HINT: All this can TOTALLY be a do-ahead!!!
Coat a large saute pan with olive oil, add the onion, season with salt, and bring to medium heat. Cook the onion until soft and very aromatic, 8 to 10 minutes.
Add the cherry peppers and corned beef and cook until the beef is just beginning to brown and the peppers are very fragrant, about 1 minute. Pour in the pickling liquid and cook an additional 30 seconds. Add the potatoes and cook 1 to 2 minutes before stirring in 1/2 cup water. Continue to cook until the liquid cooks out, 2 to 3 minutes. Press the mixture against the bottom of the pan, turn the heat to high and cook another 4 to 5 minutes without stirring to get a nice brown, crispy bottom.
Reseason if needed. Remove from the heat, toss in the parsley and serve with 2 eggs fried over easy per person.
