Place a small saucepot with water over high heat and bring to a boil.
Place a medium size saucepot over medium heat and add the chicken broth.
While the broth is coming to a simmer, combine the ground chicken, grated carrot, grated onion, grated garlic, Parmigiano, bread crumbs, parsley, salt and pepper in a medium-size mixing bowl.
Add the orzo to the boiling water and cook about 2 minutes less than the directions on the box -- the hot broth in the thermos will finish the cooking. If you are making it to eat right away, cook the orzo for the appropriate amount of time. Strain orzo when it is finished cooking and reserve.
