Preheat your oven to 400°F (200°C).
- Toss the cubed butternut squash or sweet potato with 1 tablespoon of olive oil, a pinch of salt, and pepper. Spread them out in a single layer on a baking sheet. Roast for 25–30 minutes, or until tender and lightly browned, stirring halfway through.
- While the vegetables are roasting, prepare the salad. In a large bowl, combine the mixed greens, sliced apple, dried cranberries, and toasted nuts.
- In a small bowl, whisk together the remaining tablespoon of olive oil, maple syrup, balsamic vinegar, salt, and pepper to make the dressing.
- Once the roasted squash or sweet potatoes are done, remove them from the oven and let them cool slightly before adding them to the salad.
- Drizzle the dressing over the salad and toss to combine.
- Top with crumbled goat cheese or feta, if using, and serve immediately.
