Popular in Mexican and Spanish cuisines, chorizo is a coarse pork sausage that's generously seasoned with garlic and chili powder. Mexican chorizo is made with fresh pork while Spanish chorizo is made with smoked pork. Smoked pork chorizo can be used in this recipe; cook only the potatoes for a few minutes, then add the sausage and continue cooking just until thoroughly heated, another 2 to 3 minutes.
Refrigerated hash-brown potatoes can be used in place of the frozen variety.
Bell pepper can be used in place of the green onions.
