Preheat your oven to 425°F.
Cut the cauliflower into florets, drizzle with 1 teaspoon olive oil, and season lightly with salt and pepper. Spread them evenly on a baking sheet.
In a small bowl, mix cumin, paprika, garlic powder, salt, and pepper.
Rub the chicken breast with the spice blend ensuring it's evenly coated.
Heat a skillet over medium-high heat with a little olive oil if desired, and sear the chicken breast for 2 minutes per side to lock in the flavors.
Transfer the chicken to an oven-safe dish and place in the preheated oven along with the baking sheet of cauliflower. Roast both for about 15 minutes or until the chicken is cooked through and the cauliflower is tender with slight browning.
While cooking, prepare the creamy sauce by stirring the nonfat Greek yogurt in a small bowl. If you’d like a thinner sauce, you can add a splash of water or lemon juice.
Remove the chicken and cauliflower from the oven. Drizzle the Greek yogurt sauce over the chicken or serve it on the side as a dipping sauce.
Plate the chicken alongside the roasted cauliflower and enjoy your nutritious, protein-rich meal.
