Prick potatoes several times each with a fork and microwave on high for 10 to 12 minutes. Cool potatoes until you can handle them and chop.
Heat a medium nonstick skillet over medium-high heat with extra-virgin olive oil and butter. Add apples and onions and cook 5 minutes, add potatoes and season with salt and pepper, to taste. Crisp and brown the potatoes with apples and onions 5 minutes more, then serve.
