This simple, quintessential summer salad is a reminder that seasonal ingredients at their very best don’t need much fussing (or much cooking at all, in this case). Here, peppery arugula and earthy goat cheese get brightened with juicy summer peaches, but the recipe can be tweaked to suit all seasons: If you can’t find ripe peaches, you can use cherries, strawberries, plums, raspberries or even cherry tomatoes in their place.
