Place a heavy cutting board on the tofu pieces. Press out as much liquid as possible by placing a pot of water on top of the board. Cut each piece diagonally to make 8 triangles. Meanwhile, soak the dried shrimp in cold water for 15 mins. Drain and save the shrimp liquid.
Chop shrimp finely.
Mix shrimp with next 7 tofu filling ingredients and 1 Tbsp of the shrimp liquid. With a small knife, cut a slit in the side of each tofu triangle. Stuff each slit with the tofu filling. Heat oil in a non-stick pan over medium heat. Pan-fry tofu with stuffing side down for about 2 mins.
