In a small bowl add the cream cheese, green onions, garlic powder and salt and beat until creamy.
Lay a wonton wrapper on a non stick surface. With your finger wet the edges of the wonton wrapper. Add about a teaspoon of the cream cheese filling and bring up each corner creating a star and seal tightly.
Spray the basket of an air fryer with olive oil spray. Add the wontons to the basket and lightly spray with olive oil. Cook at 370 degrees for 8 minutes. Check to see if they are golden and cook for an additional 2 minutes if needed.
