Preheat your outdoor grill to high heat and brush the grate with a little oil to prevent sticking.
Step 1
In a large pot, combine soy sauce, water, vinegar, honey, garlic, bay leaves, and black pepper. Bring it to a boil, then add the chicken thighs. Lower the heat, cover the pot, and let it simmer for 35 to 40 minutes.
Step 2
Take the chicken out of the pot, let it drain on paper towels, and discard the bay leaves. Meanwhile, bring the sauce back to a boil and reduce it to about 1 1/2 cups.
STEP 3
Place the chicken on the hot grill and cook for about 5 minutes on each side, until it's beautifully browned and has a nice crisp exterior.
