Preheat the oven to 180 (fan) or gas mark 6. Take the baking tray and spray the base with Frylight evenly. Cut the marrow into chunky rings, about 1 and a half inches wide. Using a cookie cutter or knife cut out the soft fleshy middles where the seeds are creating rings like donuts. Either discard the centres or keep for use in another dish.
Lay the rings out in the baking tray. Spray the rings with a little more Frylight. In a bowl mix together the veggie chilli plus the riced sweet potato. Season with pepper. Using a spoon stuff the middles of the marrow rings with the chilli mixture. If there's any left over simply add it in between the spare gaps in the tray.
Sprinkle over the paprika, cumin and chilli flakes. Season with salt. Place on the center shelf of the oven and bake for 35-40 minutes.
Remove the tray from the oven and sprinkle over the breadcrumbs and grated cheese. Return to the oven for another 15-20 minutes.
Once completely baked, leave to cool for a couple of minutes then serve up. Enjoy!
