We had rice left over from eating at Mr. Chen's, there were onions and carrots and some steamed broccoli and, of course, we always have eggs. So I chopped the onion and carrot and sauteed them, scrambled 4 eggs in a separate pan, then added the broccoli and rice along with some tamari, sesame and red pepper flakes. I ended up with enough fried rice to fill the take-out container and I had a quick homemade meal!
Once you have some of the basics, it's easy to come up with your own stuff.
