Preheat oven to 425 degrees F. Line a baking sheet with parchment paper or coat with nonstick spray.
Place sweet potatoes in a single layer onto the prepared baking sheet. Add 1 tablespoon olive oil; season with salt and pepper, to taste. Gently toss to combine.
Place into oven and bake for 20-25 minutes, or until tender.
Season chicken with salt and pepper, to taste.
Heat remaining 1 tablespoon olive oil in a cast iron grill pan over medium high heat. Working in batches, add chicken to the grill pan in a single layer and cook until golden brown and cooked through, reaching an internal temperature of 165 degrees F, about 4-5 minutes per side. Let cool before dicing into bite-size pieces.
In a large bowl, combine kale and green onions; drizzle with remaining dressing. Massage until the kale starts to soften and wilt, about 1-2 minutes; season with salt and pepper, to taste.
Divide kale into bowls. Top with sweet potatoes, chicken, rice, apple, Parmesan and almonds, drizzled with reserved balsamic vinaigrette, to taste.
For the balsamic vinaigrette
In a medium bowl, whisk together olive oil, balsamic vinegar, Dijon, honey and onion powder; season with salt and pepper, to taste. Set aside half of the vinaigrette and place in the fridge.
Notes
Use a big sheet pan. Avoid an overcrowded pan - use a large sheet pan for an even layer of sweet potato to get those favorited crispy edges.
Toss everything on the sheet pan. No need to dirty up another bowl - toss, mix, coat everything right on your sheet pan.
Use a cast iron grill pan or cast iron skillet. Cast iron skillets retain heat much better than a nonstick skillet, allowing for even cooking and a better sear for the chicken. When the weather permits, use an outdoor grill for even more smoky, charred flavors.
Use an instant-read thermometer for the most accurate results. The internal temperature of the chicken should reach 165°F. Let your chicken rest for at least 5 minutes prior to serving, allowing the juices to redistribute – this will allow for maximum flavor and juiciness.
Use extra virgin olive oil. High quality extra virgin olive oil is ideal for salad dressings.
Massage the kale. Massaging the kale softens the leaves, making them more tender and flavorful.
Make it vegetarian. Skip the chicken altogether to make it vegetarian-friendly, adding extra-firm tofu, tempeh, beans or hard-boiled eggs.
