This recipe for home fries features chunks of diced, uncooked red potatoes, yellow onions, and red and green bell peppers. A more basic version of home fries simply would be diced potatoes cooked in hot fat until tender and seasoned with salt and pepper, but the addition of vegetables (o'brien style) ups the ante on these delicious potatoes. To make things easier and to provide a little bit of extra color and texture, leave the skins on the potatoes. Red potatoes have a very thin, tender skin, so it is easy to digest and adds extra flavor.
