Gluten-free Sweet Potato and Corn Casserole

Description
You can use pumpkin in this recipe instead of the sweet potatoes, if you like, but leave out the lemon grass.

Look for cornflakes which don't contain malt. If you can't find any, instead use breadcrumbs made with gluten-free bread (home-made or from health shop).
