Half each pear lengthways. Scope out the area that holds the seeds. Place the pears in an ovenproof dish with the cut side facing up.
Mix the nuts,cinnamon and maple syrup together in a small bowl.
Spoon the mixture into the hole made by removing the seeds from the pear. Drizzle any leftover maple syrup over the nut mixture and the pears.
Put the ovenproof dish in the oven and cook uncovered for 10 minutes. Check to ensure they're not burning, and then bake for a further 5 minutes. The nut mixture should now be softly stuck together.
Gently transfer the pears halves into two serving dishes and dust with cinnamon. I love them on their own as they're so sweet, but if you want, you can serve them with vegan ice-cream.
