Preheat your oven to 400°F (200°C).
Peel the sweet potato and cut it into 1/2-inch cubes.
Toss the sweet potato cubes with 0.5 tbsp of olive oil and a pinch of sea salt on a parchment-lined baking sheet.
Roast the sweet potatoes for 20 minutes.
While potatoes roast, whisk together the cocoa powder, sea salt, black pepper, and cinnamon in a small bowl.
Pat the elk steaks dry with a paper towel and press the cocoa spice mixture firmly onto all sides of the meat.
Heat the remaining 0.5 tbsp of olive oil in a cast-iron skillet over medium-high heat.
Sear the elk steaks for 3-4 minutes per side for medium-rare, then remove from the pan to rest.
Place the asparagus spears on the baking sheet with the sweet potatoes and roast for an additional 5-7 minutes until tender.
Drizzle the honey over the resting elk steaks, then slice and serve alongside the roasted vegetables.
