Preheat oven to 400 degrees F. In a medium bowl, beat cream cheese, garlic, salt and onions until well mixed.
Whisk egg until well beaten in a small bowl.
Place one teaspoon of cream cheese mixture into the center of one wonton wrapper. Dip your finger into the beaten egg and lightly coat the outer edges of the wonton wrapper. Bring all the corners of the wonton together up to the center and pinch. Slide your fingers all the sides together to to form an "X" or star appearance, and make sure they are sealed (or else the filling may come out). You can add more egg wash if needed. Place on a lined baking sheet. Repeat for remaining wontons.
Lightly spray the tops of the wontons with olive oil spray.
Bake at 400 degrees F for 7-12 minutes or until tops are golden brown in color. Check after 7 minutes to ensure they don’t burn.
Serve with your favorite dipping sauce, out of the oven
