1. Prepare the spaghetti squash. Cut in half, and remove seeds and stringy pulp.
2. Place each spaghetti squash half face down in a microwave-safe baking dish, and fill dish with about one inch of water. Microwave on high for 10 to 15 minutes, until middle is tender and pulls apart easily.

Form turkey mixture into patties, and cook in skillet with half of the olive oil, until cooked through and lightly browned.
4. Scrape flesh of spaghetti squash with a fork to create spaghetti-like strands, and remove strands from the skin.
5. Allow squash to cool, and then squeeze the squash strands in your hands a few times over the sink to release excess water.
6. Combine drained squash strands, scallions, garlic powder, eggs, remaining salt and pepper in a large bowl.
7. Cook squash mixture in large skillet with remaining olive oil over medium-high heat, stirring frequently, for 10 to 15 minutes, until golden brown.
