Cut the eggplant and tofu into bite-sized pieces.
Sprinkle salt on the tofu, let it sit for 5 minutes, then remove excess moisture.
Heat cooking oil in a pan and cook the tofu until golden brown.
Remove the tofu and stir-fry the eggplant in the pan.
Once the eggplant becomes tender, return the tofu to the pan.
Add teriyaki sauce and stir-fry evenly to finish.
