Egg fried rice is a lovely, quick, tasty meal which will use up practically any leftovers. You don't even need an egg, though it helps.
Scramble 1-2 eggs in wok (if you have one) with no milk/butter added (in a little oil) using chopstick to stir and make it not stick. Remove and set aside.
Cook rice as usual, you can add some stock to the water if you have it. Drain and set aside.
Chop leftovers - vegetables, frozen peas/beans, ham, bacon, chicken, onion, garlic, etc.
Get your wok or large saucepan and heat up some sesame or unflavoured oil, stir fry ingredients from fridge (add raw meat first, then hard vegetables - carrots, onion - then softer vegetables - peppers, then cooked meats. Throw in some chinese type seasonings if you have any - garlic, ginger, 5 spice, etc or just a bit of pepper. Once these look cooked add the rice and the egg, splash some soy sauce on, chilli sauce if you want to, anything else you have which might go. Keep it moving until the rice takes on that "fried" kind of look.
