Preheat oven to 350 degrees F.
In a small bowl mix together olive oil and maple syrup, set aside. Arrange butternut squash pieces and apple pieces in a single layer on a baking sheet. Drizzle the oil/syrup mixture over the top, and toss well to coat. Spread pieces into an even layer. Sprinkle brown sugar over the top of the squash and apples.
Place in oven and bake for 25-30 minutes; flipping once at the halfway mark.
Remove from oven and sprinkle toasted pecans over the top.
Serve and enjoy!
