Preheat your oven to 400°F (200°C).
Cut the acorn squash in half and remove the seeds. Place the squash halves, cut side down, on a baking sheet. Roast in the preheated oven for about 25-30 minutes or until the squash is tender.
While the squash is roasting, rinse the quinoa under cold water. In a saucepan, combine the quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for 15-20 minutes or until the quinoa is cooked and the liquid is absorbed.
In a skillet, heat olive oil over medium heat. Add chopped red onion and garlic, sautéing until softened. Stir in cranberries, chopped walnuts, coconut aminos, maple syrup, dried thyme and sage. Add a pinch of cayenne. Cook for an additional 2-3 minutes.
Combine the cooked quinoa with the sautéed cranberry-walnut mixture, Season with salt and pepper to taste. Mix well.
Once the acorn squash halves are tender, turn them cut side up. Spoon the quinoa mixture into each squash half, pressing it down gently.
Return the stuffed acorn squash to the oven and bake for an additional 15-20 minutes or until the filling is heated through and slightly crispy on top.
Remove from the oven, garnish with fresh parsley, and serve warm. Enjoy your delicious Vegan Cranberry Walnut Quinoa Stuffed Acorn Squash!
