(1) Bring a pot of salted water a boil. Add the cubed potatoes and simmer them until they are fork tender (8-10 minutes roughly). Drain the potatoes and set aside. (2) Measure out 1 1/2 cups if the chorizo that you made. Heat a large non-stick or cast iron pan over medium heat. Add the chorizo and onion; cook for about 10 minutes while stirring periodically to ensure the sausage breaks apart. If there is excess fat in the pan from the rendered sausage, drain all but about 1 tablespoon. (3) Add the potatoes to the pan and cook while stirring periodically until the potatoes start to brown (about 8 minutes). With the back of your spatula or spoon smash the potatoes a little and stir until the mixture holds together a little. It should resemble canned corned beef hash. Set to the side to cool.
