Preheat the oven to 220°C (425°F).
Peel and dice the squash. Place the squash cubes on a baking tray lined with parchment paper. Drizzle with olive oil, sprinkle with a pinch of salt, and toss to coat evenly. Bake for 25 minutes, or until the squash is tender and roasted.
Transfer the roasted squash cubes to a blender. Add the ½ block of Jean-Jacques (cut into pieces), soy cream, minced garlic, cumin, salt, and pepper. Blend until smooth and creamy.
Cook the gnocchi in a pot of simmering water, following the package instructions.
Drain the gnocchi and mix with the squash cream to coat evenly.
Serve the gnocchi on a deep plate. Drizzle with a touch of cream, and garnish with pumpkin seeds and chopped chives.
