Rehydrate the textured soy in hot broth for 10 minutes (alternatively, you can use hot water), then let it drain for 2 minutes (don't squeeze). In the meantime: mince carrots, celery and onion; roughly blend the seitan.
In the pan, heat up some oil, then add minced vegetables, soy and seitan and leave to take on flavour for 5 minutes. Simmer with the wine until reduced. Transfer everything in the bowl and leave it to cool down. Meanwhile, you can pit the olives (see below).
When the filling has cooled down, blend it with the hand blender, then add nutritional yeast and breadcrumbs. Add a pinch of salt, nutmeg and cloves. The mixture should be consistent and compact.
Prepare the olives
Pit the olives: using the knife, cut the olive in a spiral way starting from the top, making sure not to break it (method shown in the video below).
As shown in the video below, stuff the olives with enough filling.
Prepare a batter with chickpea flour and water. Dip each olive in the batter, then roll it in some breadcrumbs (repeat the dipping and rolling a second time for a thicker and crunchier result).
Deep fry and serve
Heat up some oil for frying in a small pot and when it's hot, immerse the olives (make sure they are fully immersed, otherwise the bread may split in half). Cook until golden brown.
Serve them warm (but please, don't burn your mouth). ;)
Notes
* Ingredients and Substitutions The authentic recipe uses the Ascolana Tenera variety. But you can just stick with the biggest, greener, sweeter and most tender olives you can find. If you have little time you can also opt for pitted green olives in a can. Don't expect the same result, but they will still taste good.
