Preheat the oven to 400 degrees. Peel and dice sweet potatoes into about 1” cubes, toss in a bowl with olive oil and salt and pepper. Spread out on an even layer on a baking sheet lined with foil, and bake for about 30 minutes, flipping potatoes halfway through.
While the potatoes are roasting, divide your chopped mixed greens into four containers. Divide the remaining ingredients evenly amongst the four containers of greens: the shredded chicken, pepitas, dried cranberries, feta and sliced apple.
When the sweet potatoes are finished and are fork tender, let them cool before adding to each salad. Add your favorite healthy dressing of choice as you eat your salads throughout the week!
