Toss the squash, aubergine and chickpeas with a little oil and season with cumin, salt and freshly ground pepper.
Spread out on a baking tray lined with baking paper and roast in a preheated conventional oven (top and bottom heat) at 220°C for about 25-30 minutes. Leave to cool slightly on the tray.
Meanwhile, mix the ingredients for the vinaigrette and season to taste with salt and freshly ground pepper.
Combine the kale, squash, aubergine, chickpeas, feta and almonds in a bowl and toss well with the vinaigrette.
Serve straight away, or keep chilled until ready to serve.
