For the meatballs
Place all ingredients except bread in a large bowl. Squeeze milk from bread and break apart. Add to the bowl and mix until ingredients are thoroughly combined. Form into meatballs (we used 1 1/4-inch melon baller). Place meatballs in large pot of boiling water for about 5 minutes. Remove meatballs with slotted spoon and set aside. Makes about 3 dozen 1/2-inch meatballs.
For the broth
Place chicken, quartered onion, cut carrot, celery leaves, peppercorns and water in a large pot with lid. Bring to a boil then lower heat and simmer until chicken is tender, about 3 hours. Remove chicken from broth and cool. Remove the skin and bones and cut meat into small pieces. Set aside. Strain broth and return to pot. Add diced celery, grated carrots, diced onion and bouillon cubes. Simmer 20 minutes. Add escarole, chicken, meatballs and simmer 10 minutes. Adjust seasoning to taste.
Yields 6 quarts.
