Prepare the Dough:

1. In a large mixing bowl, combine melted jaggery and oil.
2. Mix in corn flour (if using), followed by the wheat flour.
3. Knead until the dough is soft, smooth, and not sticky. Set aside.

Prepare the Filling:

1. Grate or finely chop all the vegetables and tofu.
2. Place in a pot, season with salt, and steam over medium heat until the moisture evaporates.
3. Stir in the olive oil, then remove from heat and let cool.

Assemble the Pies:

1. Divide the dough into equal portions and roll each into a ball.
2. Lightly oil your work surface and rolling pin.
3. Roll each ball into a not-too-thin flat disc.
4. Place the dough on a pie maker or baking tray.
5. Add a spoonful of filling to one side of the dough, then fold and seal the edges.
6. Repeat with remaining dough and filling.

Bake:

1. Preheat your oven to 180°C (350°F).
2. Bake pies on the middle rack for 40–45 minutes, or until golden brown.
3. Test doneness with a fork — it should come out clean.
