Meanwhile, mix together the drained chickpeas with the olive oil, paprika and salt. Air fry for 20 minutes, turning every now and then, until crispy (either slide the lamb chops to one side or cook on a separate shelf).
For the tomato and aubergine stew: heat the oil in a large non-stick frying pan, add the onion and sauté for 5 minutes or until starting to soften. Add the peppers, aubergine and garlic, then continue to cook for 5-10 minutes, stirring occasionally, until soft.
Add the chopped tomatoes, capers (if using) and parsley. Stir well and bring to the boil. Reduce the heat and gently simmer for 5-10 minutes. Season to taste with salt and freshly ground black pepper - if using capers, go easy on the salt as they are already quite salty.
Meanwhile, mix together the remaining Greek yoghurt and zest of a lemon.
Serve the lamb chops, some stew, sprinkle with chickpeas and a dollop of lemony yoghurt.
