In a large bowl combine butternut squash, oil, garlic powder, and salt. Toss until combined and then spread along a large sheet pan. Bake for 25 minutes.
Once butternut squash is baked, slice the sourdough loaf into slices and toast.
Spread bread slices with a layer of ricotta, top with baked butternut squash, and sprinkle with pomegranate seeds and sage. Enjoy!
