Orzo with Asparagus and Goat Cheese

Cook orzo in salted water as package directs, adding asparagus to water 3 minutes before orzo will be done. Reserve 1/4 cup orzo cooking water and then drain orzo and asparagus; return orzo and asparagus to pot. Add tomato, cheese, zest and pepper to pot; toss to coat. Stir in enough cooking water to create a creamy sauce.
