Fresh wedges of tomato, thinly sliced onion and sliced cucumber dressed simply with vinegar and oil makes the most simple salad possible—think of it as the Southern counterpart to the classic Italian tomato-and-mozzarella salad. It is best enjoyed at the height of summer, when tomatoes and cucumbers are fresh from the garden.
Whisk vinegar, oil, honey, salt and pepper in a large shallow bowl.
Remove alternating stripes of peel from the cucumbers. Slice the cucumbers into thin rounds. Add the cucumber slices, tomatoes and onion to the dressing; gently toss to combine. Let stand at room temperature for at least 30 minutes and up to 1 hour.
