Preheat the oven to 425 degrees F. Line a baking sheet with parchment paper (I never like to cook with aluminum foil).
Scrub the squash and dry it. Cut into half lengthwise, and scrape out the seeds. Smear the 1 Tbs. of coconut oil all over the skin and season with sea salt.
Arrange the squash cut side down on the prepared baking sheet. Roast for 30 minutes, or until softened. Remove from oven and cool slightly. Cut into 2-inch pieces. Note: you can eat the skin like I do, or you can slice it off! Meanwhile, heat the additional coconut oil in a pan and saute the greens quickly, until gently wilted. Season with a little sea salt and lemon juice.
Arrange the squash and greens on a plate and enjoy!
