3/4 pound Chinese barbecued pork, half cut into 1/2-inch dice and half sliced
1/3 inch thick
1/2 cup frozen peas, thawed
2 large shiitake mushrooms, stems discarded and caps thinly sliced
1 carrot, cut into 1/3-inch dice
1 head baby bok choy, halved lengthwise and thinly sliced crosswise
4 large eggs, lightly beaten
6 cups cold cooked Japanese short-grain rice
2 scallions, thinly sliced
Pinch of freshly ground pepper
1/4 cup pickled ginger
In a small bowl, stir the soy sauce with the rice vinegar, sesame oil and sugar.
Heat a very large skillet. Add the shortening and let melt. Add the diced pork and stir-fry over high heat for 1 minute. Add the peas, shiitakes, carrot and bok choy and stir-fry until tender. Add the eggs and scramble just until set.
Stir in the cooked rice, scallions, soy sauce mixture and pepper and stir-fry until the rice is hot. Remove from the heat and season with salt. Spoon the fried rice into bowls, top with the sliced pork and pickled ginger and serve.
