Stirfry, with chunks of whatever meat and veg you want.
Marineade the meat if you want, make sure it's in bitesize chunks, cook it in oil until it's nearly cooked. Add the veg that take the longest ie carrots, onion, pepper, cook for a couple of minutes, add the noodles and then after a couple of minutes, veg that don't take as long ie peas and sweetcorn.
I always make up my own sauce with stuff from the cupboard and fridge, such as soy, worcester, chilli and apple juice with pork, or you can buy packets of sauce.
