2 skinless, boneless chicken breast halves (about 2/3 pound total), fresh or frozen
Cooking oil spray (optional)
2 large eggs (optional)
2 tablespoons peanut or other vegetable oil
1 large onion (for 1 cup chopped)
1 cup already-sliced mushrooms
¼ cup dry sherry
3 tablespoons soy sauce, plus additional for serving (optional)
1 tablespoon bottled minced garlic
4 cups leftover cooked rice (regular long-grain or quick-cooking brown)
1 to 2 bunches green onions, about ¾ cup chopped
1 can (5 ounces) sliced water chestnuts
1 cup frozen green peas
1 ½ tablespoons dark sesame oil
Recipe
If the chicken is frozen, run it under hot water so you can remove any packaging. Place the chicken on a microwave-safe plate and microwave 2 minutes, uncovered, on high, to begin defrosting.
Meanwhile, if you're using the eggs, spray a 12-inch nonstick skillet with cooking oil spray and set it over medium heat. Beat the eggs lightly, pour them into the skillet, and cook without stirring (as you would with an omelet) until they are almost dry. While the eggs cook, cut the chicken (fresh or partially defrosted), into bite-size chunks. When the eggs are ready, remove them to a plate and set aside.
Heat 1 tablespoon of the peanut oil in the 12-inch skillet over high heat. Add the chicken and cook, stirring occasionally. As it cooks, peel and coarsely chop the onion, adding it to the skillet as you chop. Cook 1 minute. Stir in the remaining 1 tablespoon peanut oil, the mushrooms, sherry, 3 tablespoons soy sauce, and garlic, then add the rice and cook about 3 minutes, stirring frequently.
Slice the green onions, using the white and enough of the tender green tops to make ¾ cup. Add them to the skillet and stir well. Drain the water chestnuts and roughly chop, adding them as you chop. Add the peas and sesame oil. If using the egg, cut it into thin strips, add to the skillet, and stir. Stir-fry 1 minute more to heat the water chestnuts and peas. Serve, passing extra soy sauce at the table (if using).
