Combine spinach leaves, oranges, raspberries, blackberries and strawberries in a large bowl.
Top your salad with chopped walnuts and feta cheese crumbles.
In a medium size bowl, whisk together orange juice, olive oil, balsamic vinegar, and honey until fully incorporated.
Pour the salad dressing over the salad before serving and toss to coat.
Notes
I like to use fresh clementines (or cuties as my kids call them) for this recipe. You could also use mandarin oranges, but the flavor of the fresh fruit is so much better than the canned fruit.
