Preheat oven to 205°C.

On a chopping board, with a well sharpened knife, cut the squash in two, height wise.

Remove the seeds and the fibres from each half. Place both squash halves skin-side down on an ungreased baking sheet.

Combine the apples, butter, sugar, nutmeg and lemon juice in a small bowl. Spread the mixture in each squash half.

Cover and bake in the oven for 30 to 40 minutes. The squash should be tender when done.

Serve while the squash is very hot, as a sweet side dish, or for dessert.
