– Prepare the ginger sauce in a small bowl by peeling off the skin and grating it with a grater. Combine well the grated ginger including the ginger juice with soy sauce, mirin and sugar. Stir well and set it aside.
– Heat olive oil in a pan over medium-high heat, add pork slices, and stir-fry for 1 to 2 minutes until the meat is no longer pink. Then, pour the ginger sauce over the meat.
– Lower the heat to medium, give the meat a quick stir, and bring it to a simmer. Once the sauce has thickened and the pork is cooked through, turn off the heat and transfer to a plate.
