Even people who don't usually like squash have a soft spot for the acorn squash. The ribbed, dark-green skin of this winter squash hides a bright orange interior that is very low in saturated fat and cholesterol but packed with nutrition, including Vitamin A, Vitamin B6, thiamin and magnesium. It's also high in fiber. There are a variety of opinions about how to cook acorn squash. Some people like the old-fashioned method of slicing the squash in half, removing the seeds, filling the cavity with brown sugar and butter and baking it cut-side up. Others like to drizzle honey or maple syrup in the cavity after brushing the squash with melted butter.
