Preheat the oven to 200°C and place the butternut pieces in an oven-proof dish, drizzle with olive oil and sprinkle with the fresh/dried herbs, chilli flakes as well as salt to taste. Roast until tender (approximately 30 minutes).
When done, remove from the oven, add the spinach leaves and toss with the vegetables so the leaves start to wilt but not cook through. Add the feta and olives and ensure all components of the dish are evenly distributed.
If dry, add a light drizzle of olive oil. If using, lightly drizzle the balsamic reduction and sprinkle with pine nuts. Serve on a bed of couscous prepared according to the pack instructions.
