Cut the pumpkin in half, then cut it into smaller pieces to make it easier to peel. Peel it and scrape out the inside with a spoon. Cut it into large cubes and place them in a mixing bowl. Season with salt and oregano, add a little olive oil or pumpkin seed oil, then mix thoroughly.Quick solution: instead of peeling the pumpkin, just wash it, cut it into large pieces, and bake it with the skin on. In this case, scrape the skin into a bowl at the end and season it. This is also a good solution, but I think the first version will have a more flavorful taste.
Pour onto a baking tray lined with baking paper, spread out, and finally drizzle with olive oil or pumpkin seed oil. Bake in a 200°C (392°F) oven for about 20 minutes, or until golden brown and crispy.
