I have been making the following dish with a lot of variations lately. However, you can use any small pot.
All measurements are approximate.
Put everything except the cornstarch mixture into the pot. Bring to a boil and simmer covered for 10 minutes. Thicken the sauce with the cornstarch and serve with brown rice or Japanese soba noodles. The variations are endless. You can replace the eggplant with firm tofu cut into 1 inch cubes.
