Add prepped veggies, apples, and sausage to a large pan. Drizzle with a generous amount of oil making sure all ingredients are evenly coated. Season with garlic powder, dried rosemary, salt and pepper. Bake on 400F for 15min, with a spatula flip everything and cook for an additional 15-20min until golden. Add all tahini ingredients to a blender and pulse until smooth and creamy, add more water if needed. Enjoy!
