Preheat oven to 375 degrees.
Halve the squash lengthwise, and remove the seeds with a spoon
Bake the squash for about 1 hour, or until fork tender.
Fluff the strands of “spaghetti” with a fork by pulling the fork across the squash.
Divide the remaining ingredients ((ground turkey, ricotta + pasta sauce)) between the two halves of the squash, and sprinkle the goat cheese or mozzarella on top.
Bake until warmed through and the cheese has melted, about 20 minutes. Serve immediately.
