Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds with a spoon.
Brush the cut side of the squash with 0.5 tablespoons of olive oil and sprinkle with a pinch of sea salt.
Place the squash cut-side down on the baking sheet and roast for 35 to 40 minutes until the skin is easily pierced with a fork.
While the squash is roasting, heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Add the ground turkey to the skillet, breaking it into small crumbles with a wooden spoon, and cook until it is browned and no longer pink.
Stir in the minced garlic, sea salt, black pepper, and red pepper flakes, and sauté for 2 minutes until the garlic is fragrant.
Once the squash is finished roasting, use a fork to scrape the flesh into long, spaghetti-like strands.
Transfer the squash strands directly into the skillet with the turkey and toss well to combine.
Stir in the fresh parsley, basil, lemon zest, and lemon juice, and cook for another minute until everything is hot and well incorporated.
