Preheat oven at 220ºC / 430ºF. Peel the pumpkin, remove seeds, cut into cubes and place them on a baking sheet lined with parchment paper. Drizzle with olive oil and season with salt and pepper. Bake for 20 minutes, or until tender and the edges are golden.
For the vinaigrette, whisk together all the ingredients and reserve.
To serve the salad, arrange the greens and pumpkin on a serving plate. Drizzle with the vinaigrette, top with cheese, pitted chopped dates, pomegranate and sunflower seeds.
