In a large pot, combine the chicken thighs, ginger, scallions, water, and salt. Bring to a boil over medium-high heat.
Once boiling, reduce the heat to low and cover the pot. Simmer gently for about 30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F.
Remove the chicken from the pot and let it cool slightly. Strain the broth and reserve it for another use or discard.
Once the chicken is cool enough to handle, remove the skin and bones, and slice the meat into bite-sized pieces.
In a small bowl, mix together the soy sauce, sesame oil, and rice vinegar. Drizzle this sauce over the sliced chicken before serving.
