Well I quite often make a basic stir fry, which is basically put some oil in a large non stick pot (I don't have a wok). Get it hot and add onions, celery, peppers, and whatever other vegetables I have (a bag of frozen works, if I don't have fresh). I saute till crisp/tender, then add a sauce made of soy sauce, a little cornstarch and some sugar or honey. Serve it over rice. You could add meat or shrimp (or tofu) as well.

For Lo Mein - you can use any kind of noodles (I've used spaghetti!)if you don't happen to have the real chinese noodles. Cook the noodles, sauté assorted veggies (onions are pretty much a must - the rest is at your discretion)and then I have a basic stir fry sauce that I purchase. Mix the veggies and noodles, pour on the sauce to taste, toss, and you have a reasonable approximation of Lo Mein (that is a lot less oily than what you usually get in a restaurant).

And fried rice, which I usually do when I have leftover white rice (I often freeze leftover rice for just this purpose)- again sauté the vegetables you have on hand - onions, peppers, peas are all good. When the veggies are about done, add an egg and scramble it up well, then the rice, then soy sauce - and mix it all up.

Pineapple chunks can be added to all of the above if you like - gives it more of a polynesian twist.

These aren't gourmet recipes - but they're quick and fairly healthy.
