You may boil them.
Or fry them.
Wontons are supereasy to make since you can find the wrappers at almost any grocery store. You can use my recipe for ground pork and turkey, bamboo shoots, and cabbage if you wish.
Set a pot of water to boiling, lower the heat to medium and add the wontons. When the wontons rise to the surface, they'll be done. Serve with the dipping sauce of soy sauce, vinegar, scallions, and dried chili.
If you're deep-frying them, there's no need to boil them first as you would potstickers. Set your heat at medium-low and fry until golden. I like to serve these with either the bottled sweet chili sauce or sweet and sour sauce.
