In a small jar or mixing bowl, whisk together the extra virgin olive oil, apple cider vinegar, maple syrup, Dijon mustard, salt, and black pepper until the dressing is fully emulsified.
In a large serving bowl, combine the mixed spring greens, sliced apples, dried cranberries, toasted pecans, and thinly sliced red onion.
Drizzle the prepared apple cider vinaigrette over the salad components.
Toss the salad gently with tongs to ensure all ingredients are evenly coated with the dressing.
Garnish the top of the salad with crumbled feta cheese and serve immediately to maintain texture.
