Costillas de cerdo a la Riojana is a rich Argentine dish that pairs grilled pork ribs with sautéed vegetables, fries, and fried eggs. The ingredients are typically piled together on a serving platter or a paper plate after having been cooked separately.
Pork ribs are grilled, the potatoes and eggs are fried, and a combination of strips of peppers, peas, onions, and (optional) pieces of bacon or ham is sautéed in butter. This unusual combination usually comes with the sunny-side-up egg atop the pork rib, while the other accompaniments are arranged on the side.
