Preheat oven to 400 degrees. Spray baking sheet with olive oil.

Cut the neck off the butternut squash and peel (reserve bulb portion for another dish). Using a mandolin or sharp knife thinly slice the butternut squash into chips. Place in a single layer on baking sheet and spray with olive oil. Sprinkle with seasoning. Bake for 12 - 15 minutes, depending on thickness, until just tender and beginning to lightly brown.

Remove from oven and top with crumbled bacon, scallions, and shredded cheddar. Return to oven and bake an additional 5-7 minutes until cheese is bubbly. Allow to cool slightly before topping each with a dollop of sour cream.
