Preheat your oven to 400°F (200°C). Peel and cube the sweet potato into bite-sized pieces.
Toss the sweet potato cubes with olive oil, sea salt, black pepper, and garlic powder on a parchment-lined baking sheet.
Roast the sweet potatoes for 20-25 minutes until they are tender and slightly caramelized on the edges.
While the potatoes roast, season the chicken breast with a pinch of salt and pepper, then grill or pan-sear over medium heat until the internal temperature reaches 165°F. Let it rest for 5 minutes before slicing into strips.
Place the chopped kale in a large mixing bowl and massage it with a small splash of lemon juice for 1 minute until it becomes soft and dark green.
In a small jar or bowl, whisk together the Greek yogurt, tahini, and the remaining lemon juice until smooth and creamy.
Add the cooked farro, roasted sweet potatoes, and sliced chicken to the bowl with the kale.
Drizzle the creamy dressing over the salad and toss gently to combine all ingredients before serving.
