The Dish: Tortilla Soup. Seasoned chicken stock is the foundation of this Southwestern staple, to which executive chef Emiliano Ramirez adds sautéed celery, carrots, yellow and green squash and fire-roasted tomatoes. Next come strips of chicken breast that Ramirez has grilled separately. It is the garnish, though, that brings the soup to life: pico de gallo (Spanish for "rooster's beak," the name reportedly derives from the red chilis used, which resemble a rooster's beak). Ramirez's pico de gallo is a lively mixture of chopped tomato, onion, avocado, cucumber and mild or volcanic peppers, to which he adds lime juice, cilantro and a sprinkle of salty chili powder. Quartered limes are served on the side, as are homemade, fried, warm tortilla strips.
