Add all ingredients for the vinaigrette to a small blender and blend until thick and completely smooth. Refrigerate until ready to use.
Roast the butternut squash and chicken:
Preheat the oven to 400 degrees F.
Spread the butternut squash over a baking sheet. Drizzle with olive oil and sprinkle with sea salt and cinnamon. Toss everything together using your hands until everything is well coated.
Place the chicken in a casserole dish. Drizzle with olive oil, dried oregano, paprika, and sea salt. Use your hands to mix everything together so that all tenders are well coated in oil and spices.
Roast the butternut squash and the chicken in the oven for 22 to 25 minutes, or until the butternut squash is golden-brown and soft on the inside, and the chicken tenders are cooked through (internal temperature of the chicken should be 160 degrees F.). If the chicken is not finished cooking after 20 minutes, turn off the oven and leave chicken in the still-hot oven 5 to 10 minutes, until all the way cooked.
Prepare the Salad:
Divide the baby spinach between 4 bowls. Top with pecans, golden raisins, roasted butternut squash, chicken, and apple slices. Drizzle desired amount of vinaigrette over each bowl and serve.
Notes
*You can replace the avocado oil with almond oil, olive oil, or grapeseed oil.
