In a bowl, combine ground pork, egg, salt, soy sauce, sesame oil, minced ginger, and chopped green onions. Use a pair of chopsticks to stir all the ingredients in one direction for about 100 times until they are evenly combined.
Put 1 teaspoon of the filling in the center of a wonton wrapper. (I advise not to add more than 1½ teaspoons of the filling to each wonton wrapper; otherwise, the filling might not cook through properly when you boil the wontons.) Moisten the edges of the wrapper with water using your finger, fold the wrapper in half to form a rectangle, and press the edges to seal.
Dab a small amount of water on the bottom right corner of the rectangle, bring the two bottom corners together, sealing them to create a gold ingot shape. Repeat the process for the remaining wonton wrappers.
Add all the "Soup Base" ingredients to a large soup bowl. Set aside on your countertop.
In a medium pot, bring half pot of water to a boil. Reduce the heat to medium low. Gently add 10 to 12 wontons to the simmering water.
Cook for about 5 minutes (10 minutes for frozen wontons) or until the wontons are cooked through and float to the surface.
Ladle the wontons with the hot soup into the prepared soup bowl. Gently mix with a spoon until the salt dissolves. Serve immediately while hot.
