Peel and cube the sweet potato, then boil in a pot of water for 12-15 minutes until fork-tender.
Pat the sirloin steak dry with paper towels and season both sides with sea salt, black pepper, and garlic powder.
Heat the olive oil in a cast-iron skillet over medium-high heat until shimmering.
Place the steak in the skillet and sear for 3-4 minutes per side for medium-rare, or until your desired doneness is reached.
Remove the steak from the pan and let it rest on a cutting board for 5 minutes before slicing against the grain.
While the steak rests, steam the broccoli florets in a steamer basket for 5 minutes until vibrant green and crisp-tender.
Drain the sweet potatoes and mash them thoroughly with the ghee until the texture is smooth and velvety.
Spoon the sweet potato mash into a bowl, top with the sliced steak, and serve with the steamed broccoli on the side.
