Preheat your oven to 400°F (200°C).
Rub the chicken thigh with olive oil, garlic powder, salt, and pepper. Place it on a baking tray.
Roast the chicken in the oven for about 25-30 minutes or until the internal temperature reaches 165°F (74°C), turning once for even cooking.
While the chicken roasts, peel and chop the sweet potato into cubes. Boil the cubes in water until tender, about 12-15 minutes.
Once cooked, drain the sweet potato and mash it until smooth. Season with a pinch of salt and pepper to taste.
For the beluga lentils, if not pre-cooked, simmer them in water until tender (usually around 20-25 minutes) and then drain. If using pre-cooked lentils, gently warm them in a small saucepan with a bit of salt and pepper.
Steam the kale until just tender, about 4-5 minutes, to maintain its vibrant color and nutrients.
Plate the dish by placing the sweet potato mash as a base, arranging the roasted chicken thigh atop, and serving the steamed kale and warmed beluga lentils on the side.
Enjoy this nourishing dinner that beautifully balances lean protein, complex carbohydrates, and vibrant greens.
