Effervescent in every bite, this quintessential summer salad will instantly transport you to a farm dinner on a warm August evening. Tomato, corn, cucumber, and red wine vinegar give a sweet base to this crisp side dish, with chopped red onion and fresh basil bringing sharpness in equal parts. Cilantro, parsley, and black pepper add an earthy, herbaceous kick to round out the dish. Go ahead and try not to follow this up with a thick wedge of sweet and musky summer melon.
