Cut the pumpkin in half. Peel it and scoop out the guts, discarding the guts and peel. Cut the pumpkin into small-bite-sized cubes. You’ll need 4 cups for this recipe; you may have leftovers depending on the size of your pumpkin.
Toss the pumpkin cubes with enough extra virgin olive oil to generously coat them, along with the 1/4 teaspoon of cinnamon and salt and pepper to taste.
Pour the pumpkin cubes onto a parchment-paper-lined baking sheet. Bake at 350 degrees Fahrenheit, stirring once or twice, for 35-45 minutes or until tender and golden-brown on some edges.
