Start by adding a little oil to a frying pan dice your potatoes as desired thickness, add to pan add seasoning and diced onion and cook on low heat. About 5 minutes into cooking I add a little water and cover with a lid so they steam cook for a about 5 minutes till water is gone. Continue to cook till soft. Once done remove and add chorizo cook on low/medium heat cover with a lid stir occasionally till chorizo is cooked all the way thru.
