To make Crab Rangoon Wontons, you will need wonton wrappers, cream cheese, canned crab meat, green onions, garlic powder, salt and vegetable oil. Mix the cream cheese, crab meat, green onions, garlic powder and salt in a bowl. Take a wonton wrapper, place a small spoonful of the mixture in the center of the wrapper. Wet the edges of the wrapper with water and fold it in half diagonally, pressing the edges to seal. Repeat until all the mixture is used. Heat vegetable oil in a frying pan, then fry the wontons until golden brown. Serve hot.
