Preheat oven to 400 degrees F (200 degrees C).
In a small bowl, combine the butternut squash or pumpkin, cinnamon, garlic powder, and 1 tablespoon olive oil. Toss to coat.
Spread the butternut squash or pumpkin mixture on a baking sheet. Roast for 15-20 minutes, or until tender and slightly browned.
While the butternut squash is roasting, spread the pizza crust with the remaining 1 tablespoon olive oil.
Sprinkle the cheddar cheese over the pizza crust, followed by the roasted butternut squash or pumpkin, red onion, and gorgonzola cheese.
Bake in the preheated oven for 10-12 minutes, or until the crust is golden brown and the cheese is melted and bubbly.
Remove the pizza from the oven and drizzle with honey.
Sprinkle with the fresh sage leaves and pumpkin seeds.
Serve immediately and enjoy!
