Preheat oven to 200 C. Lightly oil a deep baking tray and place the peppers close together, cut side down. Cover with parchment and foil and bake for 20 -30 minutes until slightly soft. Remove from oven, uncover and leave to cool slightly. Lower the oven to 170 C.
In a separate tray spread the diced butternut squash and pepper tops. Drizzle with olive oil and place in same oven. Roast for 20-30 minutes until caramelised and soft. Remove from oven and cool slightly.
To prepare filling: In a large bowl mix together the cooked quinoa, black-eyed beans, spring onion, sultanas, coriander, mint, spices and seasoning. Add the roasted butternut squash and pepper tops. Gently mix and season to taste.
To fill peppers: Spoon the quinoa filling into each pepper and pack as tightly as you can. Place peppers snugly together, filled side up, in the baking tray so they don’t topple over.
Return peppers to oven and bake for 20-30 minutes until filling has heated through and peppers are shrivelled.
Serve with a crisp fresh green salad or try serving this with homemade roasted tomato sauce.
