Cut it in half and put each half face down in a dish with about an inch to 2 of water. Bake on 450 for 30-40 min. Just keep an eye on the water. Poke a few holes in the top of each half to make sure to aureate it.
You can also just line a pan with foil, put olive oil and salt and pepper in each half and bake it that way.
Add some pasta sauce and parm, like spaghetti. You can throw in some meatballs if desired. Just beware that it will have more water in it than actual pasta so your sauce can get watered down.
Or add brown sugar and cinnamon to make it as a side dish.
