Pre-heat the oven to 180°C (fan) / 200°C (conventional) / Gas Mark 6.
Slice the aubergines lengthways. Then take a knife and criss-cross the flesh. Brush the aubergines with olive oil and some of the crushed garlic and season well. Place on a baking tray and roast in the oven for 30 mins or until the aubergine flesh is soft and cooked through.
In the interim, take a frying pan, add 2 tbsp of olive oil and place on medium / high heat.
Add the onions and fry until they start to turn golden. Then add the carrot, celery and garlic (reserve a little garlic for the tomato sauce) and cook until the vegetables have softened.
Add the turmeric, smoked paprika and chilli flakes. Follow with the tomato purée and stir until evenly distributed in the mixture for a few minutes.
Add the lentils, cherry tomatoes, water and maple syrup. Reduce the heat to low and let it cook for about 5 to 10 minutes until the water has been absorbed and the cherry tomatoes have softened.
Remove the aubergines from the oven. Scoop out some of the flesh, gently taking care not to tear the aubergine cases. Add the flesh to the lentil mixture, stir and season to taste. Let the flavours of the mixture combine by gently cooking for a few minutes, stirring now and again.
Take a shallow casserole pan with a lid, place it on a medium / low heat and add 1 tbsp of olive oil and the remaining garlic. Let it infuse with the oil, being careful not to let it burn. Add the chopped tomatoes / passata, the bloomed saffron and season. Let it simmer gently for 10 mins.
Take one aubergine half and gently place it on the tomato sauce. Fill it with half the lentil mixture and then place the other half of the aubergine on top. Repeat with the other 2 halves of aubergine. Don't worry if some of the lentil mixture falls into the sauce - it will add to the overall flavour. Leave to simmer with the lid on the pan for approximately 20 mins.
Serve the aubergine garnished with fresh coriander accompanied by rice or bread and a salad with a citrus dressing. If you feel confident serve the aubergine with the split facing upwards like I have in my picture so it looks like they have been stuffed.
