11.1/2 cup fresh parsley, finely chopped
12.1/2 cup crumbled goat cheese
13.1/2 cup toasted walnuts roughly chopped-Toasting is optional but it does bring out their natural oils, enhancing their rich, nutty, earthy flavor and providing a crispier texture.

Topping

1.Pomegranate arils (optional)

Directions:

1

Step 1. Prepare the Quinoa.

Rinse 1 cup of quinoa, drain, then add to saucepan with 1 1/2 cups of water. Bring to a boil, then lower to a simmer, cover pot and let simmer for 15-20 minutes. Set pot aside.

Step 2.

Preheat oven to 400 degrees.

Cut squash lengthwise and remove seeds. Place the squash on a large rimmed baking sheet, and rub olive oil all over, then sprinkle all halves with just a 1/2 teaspoon salt. Roast cut side down until tender, about 30 minutes.

Step 3.

While squash cooks, melt 5 tablespoons butter with the maple syrup, finely chopped rosemary, and a dash of cayenne (if using) in a small saucepan over low heat until combined.  

Set aside until the squash is done.

Step 3.

After 30 minutes, remove squash from oven. Turn the squash cut-side up and brush with 2 tablespoons of the maple butter blend; reserve the remaining maple butter for serving. Return the squash to the oven and roast until slightly caramelized and very tender, 5 to 10 minutes more.

Step 4.

Finely chop the shallot and slice the mushrooms.

Melt remaining 2 tablespoons of butter in a large skillet over medium-low heat. Add the shallots and cook, stirring, until softened and translucent about 8 to 10 minutes.

Increase the heat to medium high and add the sliced mushrooms and 1/2 teaspoon salt. Sauté mushrooms until most of the liquid they release has evaporated and the mushrooms are a deep golden brown, 10-15 minutes.

Step 5.

Finely chop parsley.

Roughly chop toasted walnuts.

In a large bowl, combine the quinoa, chopped parsley, goat cheese, walnuts, mushroom mixture and 1/2 teaspoon each of salt and pepper ,and toss.

Stuff into the squash halves and drizzle with the remaining maple butter.
