Heat oven to 425°F. Toss squash with coconut oil. Stir together all the spices along with the salt and pepper, sprinkle over the squash and mix thoroughly. Spread evenly on a parchment-lined rimmed baking sheet.
Roast for 23 to 25 minutes until the squash is easily pierced with a knife, turning the pan halfway through.
While squash is roasting, pickle the POM Pomegranate Arils: combine the vinegar, fennel seeds, and salt in a microwave-safe bowl. Microwave for 30 seconds, stir in grated ginger and POM and allow to pickle until needed.
Once squash is done roasting, strain the pickled POM and use to garnish the squash along with the toasted pecans and a drizzle of maple syrup.
