On a clean work surface, follow the instructions for rolling out the pastry as given on the box.
Once an entire rectangle is rolled out, use a pizza cutter to make 12 even sections, as shown in the post photos above.
In a large bowl, mix together the ingredients for the filling using a fork. Start with the ¼ cup of tofu and onions, and add more as desired after tasting the final filling.
Once all the filling ingredients are incorporated, take 12 even portions of the mixture and place on each pastry section.
Take the four corners of each pastry and fold them up (see the picture of the finished product).
Brush butter on top of each pastry using a pastry brush.
Place each puff pastry on a baking sheet lined with parchment paper (or well-greased).
Follow the instructions on the pastry box for how long to bake them.
They will be very soft when you remove them from the oven, so let them cool down before eating.
Enjoy!
