Toss butternut cubes in 2-3 Tbsp. of avocado oil. Evenly sprinkle cinnamon and allspice, and toss until evenly coated. Lay on foil-lined sheet, 9X13 or larger, spreading pieces so they have enough space to cook. Crack salt and pepper to taste (go light and add more later if it is needed).
Roast at 425 degrees for about 40 minutes
Similarly, toss halved Brussels sprouts in 3-4 Tbsp. of oil. Spread on large, foil-lined baking sheet. Salt and pepper to taste. Roast at 425 for 30-40 minutes.
Remove from oven and allow to cool.
In large salad bowl, layer ingredients; spinach, squash, Brussels sprouts, cheese, pecans, figs, pomegranate seeds, and finally, drizzle with olive oil and balsamic glaze.
