Preheat oven to 425°F (220°C) and line a baking sheet with parchment paper.
Wash and thoroughly dry the delicata squash.
Cut each squash lengthwise and scoop out the seeds and stringy centers.
Brush cut surfaces with 1½ tablespoons olive oil and season with salt and pepper.
Place squash cut-side down on the prepared baking sheet.
Roast for 20–25 minutes until tender but still sturdy enough to hold filling.
Turn squash cut-side up and set aside.
Rinse quinoa thoroughly in a fine-mesh sieve.
Combine quinoa and vegetable broth in a saucepan.
Bring to a boil, reduce heat, cover, and simmer for approximately 15 minutes or until liquid is absorbed.
Remove from heat, rest covered for 5 minutes, then fluff with a fork.
Toast pecans in a dry skillet over medium-low heat for 3–5 minutes. Remove and set aside.
Add remaining olive oil and diced onion to the skillet.
Cook for 4–5 minutes until softened.
Add garlic and cook for approximately 30 seconds.
Stir in cooked quinoa, cranberries, thyme, maple syrup, salt, and pepper.
Fold in toasted pecans.
Remove from heat and add parsley.
Fold in most of the feta, reserving some for topping.
Spoon the quinoa mixture generously into each roasted squash half.
Top with remaining feta.
Bake for another 8–10 minutes until heated through.
Garnish lightly with fresh parsley and serve warm
