Preheat oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Dice the chicken breast and sweet potato into small, uniform cubes to ensure they cook at the same rate.
In a large mixing bowl, whisk together the olive oil, maple syrup, chili powder, sea salt, black pepper, and garlic powder.
Toss the chicken and sweet potato cubes in the spice mixture until every piece is thoroughly coated.
Spread the mixture in a single layer on the baking sheet and bake for 20 minutes until the chicken is golden and the potatoes are tender.
While the chicken bakes, place the chopped kale in a bowl and squeeze the lime over it, massaging the leaves until they are dark green and soft.
Stir the cooked quinoa into the massaged kale to create the base of your bowl.
Top the quinoa and kale with the warm baked chicken and sweet potato mixture.
Add a dollop of Greek yogurt on top to provide a cool, tangy finish to the spicy and sweet flavors.
