- Preheat your oven to 425° F. Line two baking sheets with parchment paper. Place the butternut squash on one sheet and the Brussels sprouts on the other. Drizzle each with one tablespoon of olive oil and sprinkle with salt and pepper. Bake for 25 minutes, stirring the Brussels sprouts halfway through.
- While the veggies roast, heat a large skillet over medium heat. Add the remaining 2 tablespoons of olive oil. Sauté the diced onion until translucent, then add the minced garlic and cook for an additional 30 seconds.
- Stir in the chicken sausage pieces and fresh herbs, cooking until the sausage is nicely browned on the outside.
- Add in the cauliflower rice, diced apples, chopped pecans, and cinnamon. Stir until the cauliflower rice and apples start to soften, then fold in the dried cranberries and season with salt and pepper to taste. Remove from heat.
- Spray a 9 x 13” baking dish with cooking spray. Combine the sausage mixture with the roasted butternut squash and Brussels sprouts in the dish. Bake for an additional 12-15 minutes, or until the top is toasty and golden. Serve warm, garnished with fresh herbs if desired.
