Preheat oven to 450°F. Line a large baking sheet or broiler pan with foil or parchment paper.
For steak, combine cumin, salt, and pepper in a small bowl. Rub both sides of the steak with spice mixture. Set aside.
In a large bowl, toss sweet potato cubes with olive oil, salt, and ground cumin and chili powder. Spread potatoes across the lined baking sheet. Bake for 15 minutes. Turn potatoes and move them to one side of baking sheet.
Increase oven temperature to HIGH broiler setting. Toss green beans with remaining olive oil, garlic powder, and salt. Place beans next to potatoes on opposite side of lined baking sheet. Place steak on an uncoated wire rack on top of the sheet pan, positioning the steak so that it is over the green beans.
Broil steak on lower rack of oven for about 7 minutes. Turn steak, and broil an additional 4-5 minutes for medium rare (145°F) to medium (160°F) doneness. Remove steak from wire rack and let it sit for about 3 minutes before cutting into 5 portions or slicing against the grain. Toss green beans with pan juices.
