First, carefully cut the squash in half and scoop out the seeds and innards. This part kind of smells like autumn, because it reminds me of carving pumpkins.
Lightly coat the inside of the squash in a couple teaspoons of olive oil. Bake at 375°F for about 45 minutes, until the inside is easy to shred with a fork. Allow to cool. Scoop out the insides.
Scoop out the insides and place on a plate or baking dish with paper towels. We want to try and soak up any excess moisture from the squash.
In a bowl, mix together the squash, egg, and spices. Set aside.
Preheat the oven, with the baking sheet inside, at 400°F. Once the oven is hot enough, remove the pan, cover with parchment paper, and spread the spaghetti squash mixture over the baking sheet in a thin layer.Bake until the edges begin to brown, around 20-25 minutes. Cover in a little sauce (I used store-bought), cheese, and your favorite toppings. Bake for another 4-6 minutes, until the cheese is nice and melty.
