Mix the ground pork, green onions, soy sauce, sesame oil, garlic, ginger, and cornstarch together until well combined.
Place a wonton wrapper on a cutting board. In the center of the wrapper, add one teaspoon of the ground pork mixture. Dip your finger in a small bowl of water and trace two adjacent edges of the wrapper.
Fold the wonton wrapper over, sealing it into a triangle shape.
Then, pull the corners down to overlap and seal with water. Repeat with the remaining filling and wrappers.
Heat a large pot or deep pan with about three inches of oil to 375°F. Fry the wontons in batches (don't overcrowd the pot) for three to four minutes, or until they are golden brown in color.
Drain on paper towels, and repeat the process until all the wontons are fried.
Serve the wontons hot with your favorite dipping sauce. Enjoy!
