Ingredients
Bones of a leftover turkey
1 sliced medium onion
1/4 cup chopped fresh ginger
6 smashed garlic cloves
1/2 teaspoon red-pepper flakes
1 Napa cabbage, thinly sliced (about 6 cups)
4 ounces Asian rice noodles
2 tablespoons rice vinegar
1 tablespoon soy sauce
Coarse salt
Cilantro sprigs, for garnish (optional)
Lime wedges, for garnish (optional)
Preparation
Break up turkey bones; place in a large pot with onion, ginger, garlic, and red-pepper flakes. Add enough water to cover (10 to 12 cups); bring to a boil. Reduce heat to medium-low; simmer, partially covered, 30 minutes.
Discard large solids; strain broth through a fine-mesh sieve into a large saucepan (you should have 8 to 10 cups). Return to a boil. Add sliced cabbage to broth along with rice noodles, vinegar, and soy sauce.
Simmer until noodles are just tender, 2 to 3 minutes. Season with coarse salt. Serve garnished with cilantro sprigs and lime wedges, if desired.
