Pour a couple inches of water into a large flat-bottomed bowl or shallow dish. One at a time, place a rice paper wrap in the water and let soften, just until it becomes pliable (this step is important! Do not let the paper become completely soggy or the rice paper will split while baking. There should still be some pattern visible on the surface). Remove from water and place rice paper on a clean, flat surface. Using a very sharp knife or a pizza cutter, slice the rice paper circle in half. On both halves, place a generous scoop of the filling. Fold the bottom corner about a third of the way up the round side of the half, followed by the top corner to meet the base of the fold you just made, creating a triangle. Fold the round edge up onto the top of the package to seal it, and flip it over. This is now the top of the samosa. Repeat steps with the remaining rice paper and filling.
