Preheat the oven to 400℉. Wash, pierce and roast the sweet potatoes on a foil lined pan in the oven for approx. 45 min.
I seasoned the turkey breast liberally with kosher salt and Rickard Ultimate Chicken Seasoning. My cast iron was smoking hot with a tablespoon of canola oil. Place the turkey breast in the pan. Season the other side of the breast. Be patient before your flip it over, once the breast no longer “sticks” flip it over. Place the pan in a 400 degree oven. The turkey breast I had purchased was very large (no bone or filet attached). I checked and flipped it again at 10-12 minutes. An internal cooking temperature of 165 ℉ (74 ℃). Remember that it will continue to cook as the breast rests.
While the turkey breast is roasting, place washed baby spinach in a large frying pan on high. It is not necessary to add any liquid to the pan for spinach, there is plenty naturally. Steam cover until “almost” cooked and shut off to finish. Don’t over cook.
Once the turkey breast is done and has rested slice and serve with drained buttered spinach and roasted sweet potato.
