    • 3 cups chopped kale (about 1 small bunch)

    Preparation

    Spaghetti Squash

    1
    1. Preheat the oven to 400 degrees F.
    2. Wash the spaghetti squash and cut each in half lengthwise. Cut carefully.
    3. Using a large spoon scrap out the seeds.
    4. Drizzle flesh side of squash with olive oil, then season with salt and pepper. 
    5. Place the squash, flesh side down, on a lightly oiled rimmed baking sheet.
    6. Bake for 30 minutes.
    7. After 30 minutes take the squash out of the oven and test for doneness. Using a fork, you should be able to scrape the squash into strands. If not yet done, place back in the oven for another 5-10 minutes. Since this will be baked again, it is better to slightly undercook the squash so it won’t be mushy.
    8. When done, remove from the oven and set aside.
    9. Lower the oven to 350 degrees F.
    10. When squash is cool enough for you to handle, use a fork to scrape out all of the squash onto the rimmed baking pan, breaking apart the strands.
    11. Set aside for later.
