Prepare the filling as per the bolognese sauce, however it must be semi dry.
Steam and mash the potatoes, add salt, a dash of mustard, some soy milk and mix well. Cut the brinjals into thin slices. Preheat the oven to 190 ºC. In a baking dish, spread a thin layer of the mashed potato. Add a layer of the bolognese sauce and a layer of brinjals above it. Spread a second layer of bolognese sauce and spread the mashed potato on top of it. Sprinkle with bread crumbs and a little basil and oregano.
Bake in the preheated oven for 30 minutes, until the bread crumbs turn brown.
