In food photography, the best shots are the result of a perfect coming-together of basics - a visually appealing subject, balanced composition, and good lighting. If a photo requires too much editing after the fact, it probably wasn't a good photo to begin with.
The same principle applies to food. The most delicious dishes are the result of the right combination of ingredients. Some foods are just meant to go together. Arugula and cherry tomatoes are two such foods. The sweet and acidic juiciness of the tomatoes balance the deep, peppery bitterness of the arugula, and a touch of sea salt and olive oil pull it all together.
Be careful - this simple but spectacular salad might steal the show at dinner.
