Cut the squash in half lengthways. Remove the seeds. Place them cut side down on a baking tray. Bake in the oven for 30 minutes at 190 C.
Take the squash out and transfer them to a chopping board, cut side down. Use a sharp knife to score and thin lines through the squash being careful not to cut right through.
Put the squash carefully back in your baking tray. Mix together the rest of the ingredients except the lemon and pine nuts. Spoon the oil mixture over the squash. Then place sliced lemons around the tray. Bake again for 20 minutes at 190 C.
To serve, place the lemon slices on top of the squash halves and scatter with raw pine nuts.
