What you need:
1 Spaghetti Squash
1 jar of pasta sauce
Italian sausage, meatballs or ground beef
I cooked my spaghetti squash in the microwave since that's the way my mom always cooked it, but the food network says you can also bake it in the oven or boil it in a pot.
I placed my squash in a corningware dish with about an inch of water in it and used a large knife to make three slits in the top to help it steam. Then place saran wrap loosely over the top (so it can rise) but make sure it is secured on all sides.
The after picture (I forgot to take one before)
Cook on high 20-30 minutes, until it is soft and dents when you lightly push on it.
When it is cool enough to handle place the squash on a cutting board and slice in half lengthwise. Spoon out the seeds in the middle and the "gunk". Be careful not to scoop out the actual squash.
After the seeds are out, spoon the "spaghetti" out of the squash and top with sauce and meet.
