Don't try to make a good stir-fry, find out a place that's supposed to have awesome stir fries and start with that. It's easy to fuck up when you don't know what you're doing, being scared to turn up the heat and having everything become flaccid and flat, not know how to thicken the sauce, etc.
If you want something easy I have a recipe for you.
Cabbage & ground pork / sausage
Ingredients:
Cabbage
one of those 1lb breakfast sausage packs
butter
pepper
Directions:
Heat large (12in) pan.
Chop cabbage in half and peel individual leaves till you get a good mound. Wash and set aside.
Cook sausage, use spatula to separate sausage into relatively small bits. Set aside on a plate with a paper towel on the bottom. Wipe off excess grease from pan. Don't try to degrease the sausage beyond the paper towel.
Place about half of your cabbage leaves on the pan.
Throw in sausage.
Layer rest of the cabbage.
Throw in a TBSP of butter on top.
Set on mid-low heat and cover. if you used most of the cabbage lid might be lifted off the pan a bit, that's OK. Come back in 25mins and stir. Another 20 mins or so, grind some pepper on top of the mixture and you're done. Eat by itself, or top with ketchup.
You can do the same recipe w/ bacon instead, just cut to small chunks and cook long enough that it's heated thru. The synergy of cabbage and meat is fucking amazing, and this takes no effort.
