Combine the vegetable broth and milk in a medium saucepan and bring to a boil.
Add the orzo and cook for 8-10 minutes, stirring occasionally.
Reduce the heat to medium-low and add the Parmesan and spinach. Keep cooking for about 3 minutes, until the spinach wilts down.
Taste the orzo. Add salt and pepper to taste. Stir, and remove from heat. Serve.
