Cut the eggplant and tofu into bite-sized pieces.
Remove excess moisture from the tofu using a kitchen towel.
Heat cooking oil in a pan and cook the tofu until golden brown.
Take out the tofu and stir-fry the eggplant in the pan.
When the eggplant becomes tender, add the cooked tofu and sauce, then stir-fry together.
Serve on a plate to finish.
