Preheat your oven to 400°F (200°C). In a large bowl, toss the diced pumpkin with olive oil, cinnamon, cumin salt, and pepper until evenly coated. Arrange the seasoned pumpkin in a single layer on a baking sheet lined with parchment paper. Roast the pumpkin for 10-15 minutes, until tender and lightly browned. Then remove it from the oven and let it cool for a few minutes.
Prepare the Lemon dressing by whisking together the olive oil, honey, lemon juice, salt, and pepper in a small bowl.
In a large bowl, combine the roasted pumpkin, arugula, pear slices, raisins and walnuts.
Drizzle the dressing over the top of the salad and toss to coat everything evenly. Serve and enjoy!
