Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
Add the sweet potatoes to a large mixing bowl.
Add 2 teaspoons olive oil, ½ teaspoon chili powder, ½ teaspoon cumin, ¼ teaspoon salt, and ¼ teaspoon black pepper. Toss until the sweet potatoes are evenly coated.

Remove the baking sheet from the oven.
Turn the sweet potatoes with a spatula. Arrange the chicken in a single layer on the empty side of the baking sheet.
Bake for 18 to 20 minutes, or until the sweet potatoes are tender and the chicken reaches an internal temperature of 165°F.
Drizzle 1 tablespoon lime juice over the cooked chicken.
Add the Greek yogurt, 2 tablespoons lime juice, 2 tablespoons cilantro, water, garlic powder, and salt to a small bowl. Whisk the sauce until smooth.

Notes
Tips and Tricks
Cut the sweet potatoes evenly - Keep the cubes close to ½ inch so they become tender in the listed cooking time.Avoid crowding the baking sheet - Leave a little room between the chicken pieces and sweet potatoes so they roast instead of steaming.Check the chicken carefully - Test one of the thickest pieces with an instant-read thermometer. It should reach 165°F.Add avocado just before serving - Freshly diced avocado has the best color and texture.Adjust the sauce consistency - Add another teaspoon of water if the cilantro lime sauce is thicker than preferred.
