This recipe looks like a bog standard veg tagine dish but it really is lovely, greater than the sum of its parts. It works even if you don’t have a few things to hand: no fresh coriander, nuts or lemons. Plain couscous is fine. We’ve tried substituting carrots for the peppers and butter beans for the chickpeas (dice the carrots small as they take a while to cook.) So, next time an aubergine appears in your veg box, we cannot recommend this dish enough! Recipe based on one from bbc.co.uk/food.
