Preheat oven to 425˚. Toss butternut squash with olive oil, black pepper, and sea salt. Spread into a single layer in a roasting pan or on a baking tray. Bake until butternut squash is tender and lightly browning, 30-35 minutes.
Remove from oven and toss butternut squash with honey and scallions until butternut squash is coated. Add in quinoa and pecans and stir.
In a large bowl, combine arugula with butternut squash mixture and feta. Drizzle with olive oil and toss everything together.
