This side dish is a great way to use leftover baked potatoes.
Serves 4
Heat the oil and butter in a skillet. Add the onions and cook until soft and lightly browned. Remove the onions from the pan with a slotted spoon. Reserve. Slice the potatoes into 1/4-inch slices. Add to the hot pan and brown on both sides. Return the onion to the pan, toss and season. Serve warm.
