In a large high sided skillet, melt about 2-3 Tbs Butter. Saute the onion until translucent. Add potatoes and corned beef, toss to mix everything up then spread out evenly in the pan. Press down with the back of a spatula and let cook sizzle for 5-7 minutes. Turn over, toss, press down, and cook again. Continue this until the potatoes are nice and browned. If the potatoes are starting to stick, just add more butter. You could also use a non-stick pan and avoid the butter all together.
Dice sweet potatoes (or whites or reds) into 1/4″ cubes. Add them to boiling water and cook for 5 minutes. You want them to still be slightly tough. Train the potatoes very well and set aside. Season your chorizo with garlic and cook in vegetable oil in a high sided skillet until browned. Add potatoes and cook until the potatoes are browned and crispy a little on the outsides. Think of making hash-browns when you are determining the doneness of the potatoes. Dish up and top with chopped fresh cilantro.
