Preheat the oven to 200 °C (180 °C fan). Rinse the chickpeas in a sieve and pat them thoroughly dry so they roast better later.
Cut the aubergine and pepper into bite-sized cubes. Spread them out with the chickpeas on a baking tray or in a large ovenproof dish.
Add the olive oil, cumin, paprika, chilli flakes and a little salt. Mix everything well so the veg and chickpeas are evenly seasoned.
Roast in the oven at 200 °C for 20–25 min, until the aubergine is soft and the chickpeas turn golden brown. Turn once halfway through so everything browns evenly.
Stir the natural yoghurt with the lemon juice, salt and pepper until smooth. Keep chilled until serving.
Take the crispy chickpea traybake out of the oven and serve with the lemon yoghurt.
