I always use my chinese marinade recipe & mix it up with noodles & stir fry veg. & any kind of meat if you want ;
Bottle diet coke (small)
Tbspn tomato puree
Garlic/ginger- i use minced from jar-tspn
Salt/black pepper
Chinese 5 spice
Soy sauce - just a glug
Let infuse for a while,
Sling it all in a pan to boil, when you get the consistency you want- boil for longer if you want sticky ! & add to stir fry or marinade meat / tofu
