In a bowl, mix the crabmeat, cream cheese, Worcestershire sauce, garlic powder, salt, and ground black pepper. Mix well.
Prepare the wonton wrapper and beaten egg. Get 1 wonton wrapper and add 2 teaspoons of filling to the middle of the wonton.
Wet the edges of the wrapper by dipping your finger in the beaten egg. Carefully bring up the 4 edges of the wrapper, so they'll all meet in the middle. Make sure that it is completely closed. The output should be a four-sided triangle with a bottom.
Heat the oil in a pan over low heat. Then deep fry the dumplings until it turns golden brown.
Put all the crab rangoon on a clean plate and side it with finely chopped green onions.
Serve with sauce of your choice.
