Butternut Squash and Greens

This recipe was featured on the Food Network Show "The Next Food Network Star" and it is one of my favorites. The original recipe called for goat cheese, but I'm not a fan, so I substitute feta for it.

Butternut Squash
Beets Greens (any green will do)
olive oil
goat cheese
salt and pepper
walnuts
(1/2 cup chopped mint is optional)

Preheat oven to 425 degrees F.
Peel and cut butternut squash into 1/2-inch cubes. Place on 2 sheet trays, drizzle with olive oil and 1 teaspoon salt and distribute evenly. Place in oven and bake until softened and golden.
Wash beet greens and de-stem and chiffonade greens. Toast walnuts in a medium skillet over medium heat.
Remove squash from the oven and toss in beet greens, mint and goat cheese. Top with toasted walnuts. Adjust seasonings with salt and pepper, to taste, and serve warm.
