Mom used to make fried rice when she already had some cooked leftovers.
Sauté vegetables, using peanut oil. Include any of the following:
Toss in wok with cooked white rice and soy sauce. Add raw chopped green onions.
Note: Certain vegetables take longer than others to cook. You can start with carrots, onions and celery, then add bell pepper. Separately cook meat and or egg. Separately cook quick-cooking vegetables, like sprouts, snap peas, snow peas and water chestnuts. Again, if you overload the pan, things get steamy and mushy.
