Preheat oven to 425˚F.Line the cookie sheet with parchment paper.
Slice the ends off the Delicata squash (do not peel), using a spoon, scoop out as many seeds as possible.
Slice the squash into ½ inch rounds. Get rid of any leftover seeds from the squash rings.
Place on the parchment lined sheet, toss with the olive oil, maple syrup and chili powder and roast for about 30-40 minutes. The rings should be golden brown.
Remove from the oven, sprinkle with flaked sea salt, eat straight away or reheat later.
