The orzo in this salad is reminiscent of pine needles and when dressed in pesto brings a lovely green hue. Perlini mozzarella balls become ornaments, as do cherry tomatoes and ribbons of basil and pepperoni. I do not add salt as I find the pepperoni and pesto to be ample enough. Additional toppings to consider are slivers of red onion, black olives, and diced green bell pepper. I don't like balsamic vinegar, thus the lemon juice.
