Preheat the oven to 190°C.
Cut the aubergines & chilli in half, the carrots into chunks, the onion into thin wedges. Arrange them in a large baking tray. Scatter the tomatoes around them.
Mix the glaze, then coat the vegetables with it. Put the tray in the oven for 10 minutes, then pour over the tinned tomatoes. Toss well.
Bake for 30 minutes, turning the vegetables occasionally.
Drain the chickpeas, add to the tray, mix in with the veggies and cook for another 10 minutes or so, until the vegetables are tender.
Serve warm with a squeeze of lemon juice and mint leaves scattered on top.
