1. Preheat your oven to 180ºC (350ºF), on convection mode.
2. Peel the onions, cut them into julienne strips, and sauté them in a saucepan with a tablespoon of olive oil over medium heat for about 30 minutes, until they are well cooked and no longer crunchy.
3. While the onion is cooking, place the dough in a greased pie dish, prick it with a fork to prevent it from puffing up, and bake it in the oven for 12 minutes.
4. Mash the tofu with the soy cream, tablespoon of curry, and 2 tablespoons of arrowroot.
5. Season with salt and pepper, then add a pinch of nutmeg.
6. Once the onion is well cooked, mix it with the previous mixture and pour it onto the pie crust.
7. Bake in the oven for 30-40 minutes, until the center is set. Serve warm!
