How to Make It
In a small bowl, mix the ginger with the scallion, vinegar and 1/3 cup of the oil; season the vinaigrette with salt.
Beat the egg in a medium bowl. Spread the panko on a plate. Dip the tofu slices in the egg, then coat in the panko. In a large nonstick skillet, heat the remaining 1/3 cup of oil. Fry the tofu over moderate heat, turning, until golden and crispy, about 8 minutes. Season with salt and serve with the ginger vinaigrette.
