You're right, every country/region has their own version when it comes to egg rolls -- I love them all, and yours sounds wonderful! Thanks for the tip on how to get egg rolls to look nice & plump. I'm putting this comment here rather than in chat because I have two things to try with egg roll recipes, both of which will probably make you cringe, but here they are...
A non-oriental friend once shared her "trick" for getting egg rolls to stick together nicely -- a big spoonful of peanut butter, added at the end of cooking! I think she thickened the "leftover" juice in the wok with cornstarch, too, said it was too tasty to leave out.
