Chicken and Cavatelli

In a large pot, bring the broth, bay leaf, onion, celery, and carrots to a simmer. Simmer for 5 minutes. Add the sage, salt, pepper, and chicken breasts and simmer, partially covered, until just done, about 25 minutes. Turn the chicken breasts a few times during cooking.

Meanwhile, in a large pot of boiling, salted water, cook the cavatelli until just done, about 10 minutes. Drain.

In a small bowl, stir the butter and flour together to form a paste. Remove the bay leaf from the pot, push the chicken to the side and then whisk the butter mixture into the liquid. Simmer until thickened, 1 to 2 minutes. Stir in the cooked cavatelli and simmer until just heated through.
