Mix cream cheese, Monterey jack cheese, garlic, green onions, and black pepper in a small bowl.
Spoon about one tablespoon of the mixture into a wonton wrapper.
With damp fingers, fold the wonton wrapper in half to make a triangle. Make sure that all edges are sealed.
Quickly fry wontons in vegetable oil until golden brown.
I used my Fry Daddy and it made it a quick job. DO NOT put ALL the wontons together when frying them. Just fry about 7-10 at one time.
