Strain soup through a sieve. Reserve legs and thighs, and discard remaining solids. Let chicken cool slightly. Remove meat from bones, and slice.

Heat oil in a stockpot over medium-high heat. Cook spices until fragrant and mustard seeds are popping, about 1 minute. Stir in tomatoes. Cook, stirring, until liquid has evaporated, about 4 minutes. Add reserved soup, chile, and ginger slices. Simmer for 5 minutes. Skim fat. Season with salt. Stir chicken into soup. Garnish with scallions, and serve with orange wedges.
