To be honest I would cook it entirely in the microwave before you do anything else.
Spaghetti squash cooks perfectly in the microwave and is incredibly easy to prepare. Just cut it in half, scoop out the pulp and seeds, stand it on a (glass) pie plate or bowl in a puddle of water and nuke for 10 minutes. Remove the flesh with a fork in one hand and an oven glove on the other.
You can then add it to whatever recipe you are making, or just serve it on its own with fresh ground pepper and a pat of butter.
The results will look much closer to spaghetti than what you produced there.
