Add the chickpea flour to a large mixing bowl. Pour the water in whilst mixing with a hand whisk to remove as many lumps as possible. Add the olive oil and salt. Cover with plastic wrap (cling film) and let it rest for at least 2 hours.
Cut the eggplant into slices about ¼ inch or 1/2cm thick. Drizzle lightly with olive oil and grill them well on both sides. We use a ridged griddle pan.
In a small bowl or ramekin, mix the sliced garlic, chilli flakes, red wine vinegar and olive oil together. Put the eggplant in a bowl and pour the marinade over. Set aside until needed.
Pre-heat the oven to 450℉/230℃ (fan) 475℉/250℃ (static). If you are using a stainless steel pan, then you’ll need to preheat it in the oven before adding any olive oil.
If using a non-stick pan, you can add the olive oil now. I recommend adding about 2-3 tablespoons of olive oil and make sure it’s greased well up the sides.
Skim away any foam from the chickpea batter and give it a stir. Pour the batter into the pan, then bake in the oven for 20 minutes until coming away from the edges and starting to turn golden brown.
Remove from the oven, sprinkle with sea salt and let it rest for a few minutes, then while still hot, remove and cut into slices (big enough to fit your roll).
Place one slice of torta di ceci on the roll, followed by 2 slices of eggplant, then another slice of torta di ceci on top. Top with lots of black pepper and enjoy.
