Preheat your oven to 400°F (200°C).
Prepare the acorn squash by halving and seeding.
Drizzle olive oil over the squash halves and season with salt and pepper.
Place the squash cut-side down on a baking sheet and roast for 25-30 minutes.
Remove the squash from the oven, let it cool slightly, and then scoop out the flesh into a bowl.
In a large bowl, combine mixed greens, cranberries, walnuts, and the roasted squash flesh.
In a small bowl, whisk together the maple syrup and balsamic vinegar.
Pour the dressing over the salad and toss gently to combine.
Top with crumbled goat cheese before serving.
