How to Make It
In a medium bowl, mix together the turkey, eggs, garlic, onion, bread crumbs, Parmesan, parsley, 1/2 teaspoon of the salt, and the black pepper until thoroughly combined. Shape the mixture into twenty meatballs.
In a large frying pan, heat 1 1/2 tablespoons of the oil over moderate heat. Add half the meatballs to the pan and cook, turning, until browned on all sides, about 3 minutes. Remove the meatballs from the pan and drain on paper towels. Repeat with the remaining 1 1/2 tablespoons oil and the rest of the meatballs.
Put all of the meatballs, the escarole, broth, water, vinegar, red-pepper flakes, and the remaining 1 teaspoon of salt in a large pot. Cover and bring to a simmer over moderate heat, stirring occasionally. The meatballs should be cooked through by the time the broth comes to a simmer.
Wine Recommendation: Turkey is deceptively strong in flavor and can stand up to even the most powerful red wines. Here, try a raw-boned, rich petite sirah from California for a rollicking duet.
