In a small dish, combine the black vinegar with the honey and chile paste. Set aside.
For the dumplings
In a large mixing bowl, combine all of the ingredients except the gyoza/potsticker wrappers. Mix only long enough to evenly combine the ingredients.
Place several of the gyoza/potsticker wrappers on a clean, dry surface and drop about 1 ½ teaspoons of the chicken mixture in the center of each one. (If you have a cookie scoop this size, that's perfect.)
Next, wet your fingertip with water and run it along the entire edge of the wrappers (one at a time) -- this will work as glue. Now carefully, bring all of the edges together, to wrap up the chicken mixture, into a little bundle, and then gently pinch the top so it adheres together.
Coat the bottom of a medium-sized sauté pan (about 10-inch) generously with grape seed oil and place it over medium-high heat. Once it's sizzling hot, add as many of the dumplings as you can without crowding the pan -- there should be about an inch between them. (You will do this in a few batches.) Let them sauté for about 1 minute, to brown the bottoms. Then add about ¼ cup of water to the bottom of the pan, turn the heat to the lowest setting, and cover the pan with a lid or foil. Let the dumplings steam for about 3 minutes, just long enough to cook the chicken. Use a small metal spatula to lift them from the pan. Repeat this until all of the dumplings are cooked.
While they're still hot, serve them with the sauce on the side.
