Preheat the oven to 400F. Line a baking sheet with parchment paper. Add your squash to the baking sheet, cut-side-up. Drizzle 1 tablespoon olive oil into the scooped out squash and sprinkle with about 1 teaspoon salt. Use your fingers to rub the oil and salt all over the squash (including the skin). Flip the squash over (so the cut side is down), then transfer to the oven for 30-40 minutes, or until the squash is cooked through and easily pierced with a knife (this will vary depending on size).
In a large skillet over medium-high heat, add the remaining 2 tablespoons olive oil and turkey. Start breaking it up into chunks and spread into an even layer. Sprinkle the remaining 1 teaspoon salt all over the turkey. Let cook for 3 minutes, undisturbed, then continue to break up into small chunks and cook until cooked through, stirring occasionally, about 2 more minutes.
Reduce the heat to medium-low, add in the curry powder and cook for 30 seconds, stirring often. Add in the kale, soy sauce, and vinegar and cook until the kale is wilted, stirring often, about 3 minutes. Stir in half of the nuts and half of the fruit.
Flip the baked squash so they are cut-side-up. Divide the turkey mixture between each squash (if you have some leftover, save it for rice bowls or more squash). Top with goat cheese then broil them on high in the oven until the cheese is lightly browned on top, about 2 minutes (keep an eye on it!). Top with remaining nuts and fruit and a squeeze of lemon.
