In a nonstick pan, heat the oil over medium-high heat. Add the hash browns, season with a pinch of salt and cook until golden brown, stirring occasionally, about 10 minutes. Remove from the pan and place on a plate lined with a paper towel. Carefully wipe out the pan. Lower the heat to medium and cook the chorizo until crispy, breaking it up with a wooden spoon as it cooks, about 7 minutes.
If you are stuck with a bag or can of pinto beans and don't know what to do with them, all you need is a few spicy ingredients to make a whole meal you'll want to eat on repeat. Upgrading pinto beans like this is a great skill to build, because while it may seem silly to say, beans are having a moment.
That's right, bacon is great, breakfast sausage is good too, but when paired with frying eggs in a pan, neither of them really compare to chorizo. The reason that chorizo is the perfect one-ingredient upgrade for fried eggs is that the fat from the sausage is a strong flavor component that automatically adds significant depth to your breakfast meal. A couple of eggs fried in chorizo grease with some toast on the side is the stuff breakfast dreams are made of.
