The idea of this dish was to use the unbeatable flavours of the classic insalata tricolore in a new way. Aubergine was the obvious vegetable to wrap the other ingredients in.
For the sauce, soak the lentils in cold water for 30 minutes.
Preheat a dry griddle until good and hot. Trimming off the sides of the aubergines, cut each lengthwise into four nice big slices. Brush these on both sides with oil and griddle over a high heat until softened and nicely seared on both sides. Set aside to cool.
