Gyoza wrappers make a reliable substitution if you do not have wonton wrappers. They are thicker but will crisp up just as well to hold your delicious filling safely inside.
Feel free to alter the filling – sometimes I use half cream cheese and half finely chopped imitation crab, along with a minced green onion and a few drops of Worcestershire sauce as the filling.
If you have square wonton wrappers use those, else the round gyoza wrappers will work just fine.
