Add oil to a medium nonstick skillet. Bring to medium-high heat. Add frozen dumplings, placing the bottoms of the dumplings onto the skillet. Allow them to cook in oil for about 2 minutes, or until the bottoms turn a golden brown.
Pour enough water into skillet until it covers 1/2 inch of the bottom of each dumpling. Place lid over the skillet. Continue to cook dumplings about 10 minutes or until dumplings are cooked and most of the water is evaporated. The skin of the dumplings should turn from solid white to a slightly translucent white. You can test if the filling is cooked by cutting one open.
To make dipping sauce, add all sauce ingredients into a small bowl. Mix to combine. Serve with potstickers.
