Begin by poaching the chicken along with ginger, scallions, and garlic until fully cooked.
Once the chicken is done, slice it and arrange it over a bed of cool cucumbers and tomato.
For the sauce, combine tahini, soy sauce, vinegar, sugar, ginger, and garlic in a bowl and whisk them together until smooth.
This sauce is nutty, tangy, savory, and bright, making it a perfect complement to the chicken.
