Bring the steak to room temperature for 30 minutes. Meanwhile, preheat the oven to 425℉ and slice the sweet potatoes into 1/2-inch rounds.
Toss sweet potato rounds with avocado oil, salt, pepper, and garlic powder. Spread them on a parchment-lined baking sheet and roast for 25-30 minutes.
Trim the asparagus and toss with avocado oil, salt, pepper, and garlic powder. Add them to a baking sheet and place in the oven for the last 10-12 minutes of the sweet potatoes roasting.
While the veggies cook, season the steak generously with salt and pepper. Heat a cast iron grill pan over medium-high heat with a generous drizzle of avocado oil.
Sear the steak for 3-4 minutes per side. For a medium rare steak, check the internal temp and once it hits 130℉, remove from the grill. (Optional: finish in the oven for 3-5 minutes if you like more medium steak.)
Let the steak rest on a cutting board for at least 5 minutes. While it rests, I like to add a couple of tablespoons of room-temperature butter on top!
Meanwhile, top the sweet potatoes with crumbled feta and a drizzle of hot honey.
Slice the steak against the grain and serve with the sweet potatoes and asparagus. Enjoy!
