Preheat oven to 200˚C / 400˚F.
Place the Delicata squash on a baking sheet, scatter over the cumin seeds, season with salt and pepper and toss to combine. Arrange in a single layer and roast until the Delicata is tender and golden on the bottom, 18 to 20 minutes.
Meanwhile, in a large bowl (big enough for all the salad ingredients) place the dressing ingredients - garlic, ginger, mustard, miso, maple, olive oil – along with 1 tablespoon of water and whisk to combine. Season well with salt and pepper and whisk again. Add the kale leaves and massage the leaves in the dressing, rubbing the leaves a little, just enough to coat and soften the leaves slightly. Don’t overdo it as we still want the leaves to have structure. Leave the kale to sit for 10 minutes, or up to several hours.
To the kale, add the Delicata squash, persimmons and herbs, season with salt and pepper and toss to combine. When you’re ready to eat, top with nuts.
