Heat a large oven-safe non-stick sauté pan (like the
OXO Non-Stick Sauté Pan) over medium heat and add the sausage. Cook until brown and cooked through, then transfer the sausage to a plate that has been lined with a paper towel. Leaving the stove on and placing the pan back on the burner, add the red potatoes. There should be enough fat leftover from the sausage, that you shouldn't need oil or butter. If there isn't, add a tablespoon of oil or butter. Cook until the potatoes are cooked through, but still have a little bite to them. Remove the potatoes from the pan with a slotted spoon and transfer to a bowl. Set aside.
