Step 1

Cut the tofu into 1/2-inch thick slices. You can further cut the slices in half crosswise if you like smaller slices. Slice the onion, scallion, and the optional mushrooms and chili pepper.

Step 2

Combine all of the braising liquid except the perilla oil (or sesame oil).

Step 3

Spread the onion slices at the bottom of a small pot. Arrange the tofu on top, and then pour the braising liquid over. Bring it to a boil, and then reduce the heat to medium. Cook for about 5 minutes.

Step 4

Add the remaining vegetables, and drizzle the perilla oil (or sesame oil) over. Continue to boil for 5 more minutes. Sprinkle with the sesame seeds.
