Use a small knife to hollow out the tofu.
It's difficult to explain how to hollow it out, but if you make a square cut 3mm inside the tofu and then insert the knife from the side, it will be hollowed out neatly. Please check out the video on my Instagram if you'd like.

Mix the filling ingredients together and stuff into the tofu.

Add the sweet chili sauce and fish sauce and mix well. Garnish with chili peppers or red bell peppers and coriander.
