Don’t make it very often because it’s fried but this is a great General Tso recipe

for the sticky wings just egg your wings as you normally would.  I usually hit with an Asian rub that I have and make a sauce of 1/2 cup Sriracha,1/4 cup of honey and hit of soy.  Get wings to temp, sauce then back on egg for the sauce to set.   Remove then sprinkle with sesame seeds and green onion sliced thin.    

I have several woks (5, I think!) and accessories, an egg, a MacGyver'd wok stove, but somehow, I rarely cook Chinese! Been a very long time. The food shown in the links in this thread looks and sounds very appetizing. Healthy too (if I can figure out how to reduce the sodium). Gonna try. Thanks for posting.

Lately I've been clicking on a lot of EweTubes from "Marion's Kitchen".  Very high production values/photography, she knows what she's talking about, and easy to listen to (I could do without the hipster glasses).  Kind've an Asian "Chef John".

Before getting my Egg, I bet over half my meals were cooked in a wok; I love  wok cooking, for a couple more reasons than the flavors/health benefits.  First, I usually eat alone, and I cook each meal separately (no leftovers), and don't get tired of leftovers because, just by changing the veggies, or the condiments/sauces, you can get four very different meals out of a pkg of two large cheekun breasts.  Secondly, once you've made a few dishes you don't need recipes, you get a feel for what works and just wing it.  This is handy if, say, you go to the supermarket to get some whitefish, it looks a bit sickly, so you grab the fresh-looking cheekun instead; same with veggie substitutions.  I do know with kids asking what's for supper, its usually better to say "Orange Chicken" rather than "Something new, try it you'll like it".
