Line cookie sheet with cooking parchment paper. In small bowl, mix pork, onions and gingerroot.
Working with 1 wonton skin at a time, place 1 heaping teaspoon pork mixture on center of each wonton skin. Moisten edges of wonton skin with water; fold in half over filling to form triangle and seal sides. Bring 2 ends together to form a “hat” shape (see photo). Place pot stickers on cookie sheet; cover with damp towel to keep from drying out.
In Dutch oven, heat 3 quarts water to boiling. Add half of the pot stickers; boil about 5 minutes or until edges of wonton skins are clear. Using slotted spoon, remove pot stickers from water; drain thoroughly on paper towels. Repeat with remaining pot stickers.
Meanwhile, in small bowl, mix sauce ingredients until sugar is dissolved; set aside.
In 12-inch nonstick skillet, heat 2 tablespoons of the oil over medium heat. Add half of the pot stickers; cook 2 to 3 minutes or until crisp and golden brown on bottom. Turn; cook 2 to 3 minutes longer or until browned and crisp. Using pancake turner, remove pot stickers from oil; place on serving platter. Repeat with remaining tablespoon oil and remaining pot stickers. Serve warm with sauce.
