Cut the spaghetti squash (or vegetable marrow) in half vertically.

Scoop out the seeds.

Place on a baking sheet and bake at 350*F for about one hour. Use a fork to test for doneness. The outside should feel slightly soft.The meat of the squash should pull away from the edges when you put your fork in and pull.

Put a layer of shredded mozzarella cheese on the bottom of the boat, then a layer of shredded chicken.

Cover generously with your favorite spaghetti sauce then top with more cheese. I find that not all of the spaghetti sauce fits in the boats at this stage, add the rest of the sauce later, when eating your boat.

Return to the oven and bake an additional 20-30 minutes until cheese is melted and bubbly. I like to turn on the broiler at the end for a minute or so to get the cheese extra bubbly. If you use the broiler, make sure to stay attentive and don't let the cheese burn. Broiling goes very quickly.

Fluff the squash with a fork, pulling it away from the edges, and serve! Sometimes as we get deeper into the squash we find that we need more sauce, this is when you'll add the rest of it.
