I make this delicious stir fry using any spare ingredients if I have nothing else to make. Any desired ingredients can be added. This recipe can easily be adapted to serve more than 1 person.
Adapt it to your personal preferences. I found this recipe excellent in my uni days when we wanted to make a tasty meal out of soon-to-be-off veggies.
Just substitute the tofu for cooked chicken or beef and add in step 3.
