Preheat oven to 400°F (200°C).
Toss cubed butternut squash with 1 tablespoon olive oil on a baking sheet; roast for 20 to 25 minutes until fork-tender and slightly browned.
Rinse quinoa under cold water and combine with 2 cups of water in a saucepan; bring to a boil.
Reduce heat to low, cover, and simmer quinoa for 15 minutes or until water is absorbed.
Remove quinoa from heat and let stand covered for 5 minutes, then fluff with a fork and allow to cool slightly.
In a small bowl, whisk together the extra virgin olive oil, apple cider vinegar, maple syrup, Dijon mustard, salt, and pepper to create the dressing.
In a large mixing bowl, combine the cooked quinoa, roasted squash, baby spinach, dried cranberries, chopped pecans, and red onion.
Pour the dressing over the salad and toss thoroughly to coat all ingredients.
Top with crumbled feta cheese and serve warm or at room temperature.
