Cut cabbage, eggplant, and chicken breast into bite-sized pieces.
Add olive oil to a pan and cook the chicken breast over medium heat.
When the chicken breast is halfway cooked, add the eggplant and cabbage and stir-fry.
Once all the ingredients are cooked, turn off the heat and let it cool.
Place the ingredients in a bowl, add natto and soy sauce or low-sodium soy sauce, and mix evenly.
