Kale Salad with Chicken and Sweet Potato

Preheat oven to 400 degrees. On a rimmed baking sheet, toss sweet potatoes with 1 tablespoon oil, season with salt and pepper, and move to one half of sheet. Arrange chicken on other half. Bake until potatoes are tender and chicken is cooked through, 20 minutes. Let cool to room temperature; chop chicken into pieces.

In a large bowl, whisk together vinegar, mustard, and remaining 2 tablespoons oil; season with salt and pepper. Toss potatoes, chicken, and kale with dressing and sprinkle with almonds. Serve immediately.
