If they are large, you can stuff them with mince, herbed rice or whatever you like stuffing vegetables with and bake them.

You can cut them into chunks and roast them in balsamic vinegar and olive oil. This is lovely in a salad with spinach and goat's cheese or just as a vegetable side.

You can roast them, chopped into chunks, with other veg such as sweet potato, capsicum, pumpkin, garlic and onion. This is a nice dish by itself.
