Steps 3 & 4

Let your squatermelon cool for a while after removing from the oven.

 Then peel the shell away...

...and use a fork or your fingers to shred the strands of its flesh into pasta-like strands of squaghetti. 

Stop shy of the membranous center where the seeds are.

You can store squaghetti in the fridge for up to a week. When you're ready to eat it, just heat it in the microwave and serve with any pasta sauce, or stir fry with other ingredients for gluten-free fried noodles. Enjoy!
