I like to use hard tofu. I break it into irregular pieces with my hands in a bowl. Add some spices (often just some store-bought curry mix) and bake it in the oven until crisp (200 C). I use it to top rice and curries.

Otherwise, I smash it into a pulp, add spices as before, and then lay it in a thin layer on a oven tray. Cook it in the oven (200 C). It binds together into a sheet, which I put in sandwiches or use as wraps.
