Cut the thick fried tofu into 1/3 thickness. For the thicker piece, cut a square leaving a 1cm border and hollow out the center. Place this hollowed piece on top of the other tofu piece to create a container.

Finely chop the hollowed-out tofu center and place it in a bowl. Add miso and white sesame seeds, then mash and mix well.

Crack an egg into the tofu container. Poke several holes in the yolk using a toothpick. Cover loosely with plastic wrap and microwave at 600W for 3 minutes.

Place a slice of cheddar cheese on top and bake in a toaster oven for about 3 minutes until the cheese is golden and bubbly.
