Preheat a large skillet over medium heat.
Peel and dice the sweet potato into small cubes for crispiness. Add the sweet potato cubes to the skillet with a small drizzle of olive oil, seasoning lightly with salt and pepper. Cook for about 8-10 minutes until tender and crispy on the edges, stirring occasionally.
While the sweet potatoes are cooking, chop the kale, red bell pepper, and onion finely.
In a separate pan, add the lean ground elk and cook over medium-high heat until browned, breaking it up into small pieces as it cooks. Season with salt and pepper.
Once the meat is nearly cooked and the sweet potatoes are tender, add the chopped onion and red bell pepper to the elk. Sauté together for an additional 3-4 minutes until the vegetables begin to soften.
Fold in the kale and cook for another 2 minutes, just until it wilts slightly but retains its vibrant color.
Combine the cooked sweet potatoes with the elk and greens mixture in the skillet. Toss gently to mix all components evenly. Adjust seasoning with salt and pepper as needed.
Serve hot, enjoying a warm balance of savory elk, crispy sweet potatoes, and fresh, sautéed greens.
