Heat 1 teaspoon oil in a 12-inch nonstick skillet over high heat until just smoking. Add the tofu and cook, stirring occasionally, until lightly browned, 4 to 6 minutes. Transfer the tofu to a clean bowl.

Whisk the ginger sauce to recombine, then pour it to the pan and bring to a simmer and get thickened. Remove the pan from the heat and toss until all the ingredients are well coated with sauce and sizzling hot. Serve immediately.
