Start cooking the wild rice according to the directions on the package, using chicken stock for extra flavor if preferred.
Heat the oven to 375°F and line two large baking sheets with parchment paper.
Place chicken breasts on one sheet and cubed sweet potatoes on the other.
Toss the sweet potatoes with olive oil and season both chicken and potatoes generously with salt, pepper, and sprinkle the umami seasoning over the chicken if using.
Roast both the chicken and sweet potatoes in the oven for 30 minutes or until the chicken is fully cooked to 165°F internal temperature.
While the roasting is underway, chop the kale, apples, and almonds and set them aside.
For the dressing, whisk together Greek yogurt, balsamic vinegar, Dijon mustard, honey, lemon juice, salt, and black pepper in a small bowl.
Gradually whisk in olive oil until the dressing is smooth and emulsified.
Combine all the salad ingredients in a large bowl, pour the dressing over, toss everything together thoroughly, and serve immediately or store appropriately.
