I basically use whatever I have on hand - it's a great way to use left over meat. I made one the other night and it was something like this:

Steam 2 - 4 cups of long grain rice
While it's cooking make a 3 egg omelette and cut into small pieces
When rice is cooked, rinse it
Fry some chopped bacon and finely chopped carrots in a wok or large pan
Add some finely chopped capsicum
Add some let over meat (or pork pieces, or chicken pieces)
Add some peas
Add the rice and stir well
Add Japanese soy until rice is brown (can use normal soy but Japanese is really nice)
Add some chili paste or sauce to taste
Taste, and if necessary add more soy and/or chili
Add the chopped omelette and bean sprouts
Fry for about 5 mins then serve.

HTH, ours was yummy.
