Meanwhile, quarter tomatoes add to a large bowl. Peel, seed, and chop cucumber into ½ inch dice and add to bowl. Core pepper and chop into ½ inch dice and add. Add olives, herbs, cheese, olive oil and salt and pepper. Gently toss and adjust seasonings if necessary. Sprinkle with pine nuts before serving.
