Preheat oven and sheet pan to 375 degrees.
Remove pan from oven, carefully line a sheet pan with parchment paper for easier cleaning or spray with cooking oil.
Spread the potatoes on 1/3 of the pan and place in oven for about 15-20 minutes.
While potatoes are cooking, mix spices and oil together and toss on chicken and green beans. Remove potatoes from oven, add chicken and green beans to the sheet pan.
Bake another 25 minutes or until chicken reaches 165-degree internal temperature. If chicken in small, check at 13 minutes – it may be done.
Remove from oven. Salt and Pepper. Serve hot. Enjoy!
