Place potatoes to a large pot of cold water; bring to a boil and cook until tender, approximately 15-20 minutes. Drain, then lightly mash potatoes with a fork.
In a small bowl, whisk olive oil, lemon juice, honey, yogurt, basil, sea salt and pepper.
In a large bowl, combine mashed potatoes with diced pear, dried cherries and chia seeds. Add yogurt dressing; gently toss to combine. Garnish with fresh lemon zest.
