How to Make It
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.
