Heat a large skillet over medium-high heat (preferably cast iron or nonstick), add the oil, then sauté the potatoes until lightly browned and cooked through, about 10 minutes. You may need to do this in batches; don’t crowd the pan. Add a bit of salt, and pepper if you like, and toss and stir frequently.
Remove them to a plate with a slotted spoon and serve hot.
Notes
Serve these as breakfast potatoes. Toss them onto a plate for lunch, instead of fries or chips. Crispy potatoes can be a partner to so many entrees for dinner. Sprinkle them atop casseroles. They can even be added to other dishes for texture and heft.
