Prep Squash – Heat oven to 400°F (200°C). Cut squash in half lengthwise, scoop out seeds, brush with olive oil, and season with salt and pepper.
Roast Squash – Place halves cut-side down on a baking sheet. Roast for 25–30 minutes until tender and lightly caramelized.
Cook Filling – In a skillet, sauté onion and garlic in 1 tbsp olive oil until soft. Add sausage (or lentils/turkey) and cook until browned. Stir in apple, cranberries, pecans, kale, quinoa, and seasonings. Cook 3–4 minutes until warmed through.
Stuff Squash – Flip roasted squash halves cut-side up. Spoon filling into each half, pressing gently to pack.
Bake Again – Return to oven for 8–10 minutes. Top with parmesan or feta if desired.
Serve – Plate one stuffed half per person. Serve hot as a cozy, savory-sweet dinner.
