Each time I have served this salad, guests have taken a bite, paused, and tried to figure out what was adding such a refreshing note. Some have guessed that it was mint, others have not, but all have loved this unusual addition. The contrasting textures–the crunch of the romaine leaves paired with the salty creaminess of ricotta– also add to the salad’s appeal. The tomatoes provide some visual pizzazz with their rich crimson hue. It’s great as a garnish to grilled lamb chops or chicken.
