Cook the sweet potatoes: In a small bowl, toss cubed sweet potatoes with 1 teaspoon oil, salt and pepper. Air fry at 400 degrees for 10-12 minutes, or roast on a baking sheet at 425 degrees for 15-20 minutes, or until golden brown and crispy.
While the potatoes roast, make the vinaigrette by adding all ingredients into a small bowl and whisking vigorously. A jar can also be used.
To a large bowl, add the spring mix lettuce and top with salad ingredients, including the cooked, cooled sweet potatoes.
Pour vinaigrette over top of the prepared salad and serve immediately.
Notes
You can absolutely cook the sweet potatoes ahead of time. Store in the fridge for up to 3 days. Bring out of the fridge prior to assembling the salad to take the chill off!
