Been doing chowmein for a while (bean sprouts and egg noodles)
Was never really that great. A little bland even with soy sauce in it. The trick was a really good bit of oyster sauce that really made it taste more like my local chinese.
Tesco been doing a box of egg noodles for Β£1 and a large bag of mixed cabbage,onion,bean sprouts and carrots for around Β£1.25 if I recall
Also found the curry paste mike j recommended, hidden away 3 aisles away from other chinese sauces etc. Needs a dash of vinegar and oyster sauce though imo.
Also getting pretty good with the egg fried rice too using those microwave packets made by tilda except fried not microwaved, add yer own egg and a little oyster sauce.
Oyster sauce was the one thing missing from all of this as you see
Could feed 3-4 people for under a fiver, discounting the sauces as they last ages. Its ridiculous. Left over pork or chicken gets flung in too.
