Preheat your oven to 425°F.
Peel and dice the sweet potato into 1/2-inch cubes. Toss with a little olive oil, salt, and pepper, then spread evenly on a baking sheet.
Roast the sweet potato in the preheated oven for 20-25 minutes, stirring halfway through, until tender and slightly crispy.
While the sweet potatoes roast, heat a non-stick skillet over medium-high heat. Add the lean ground beef, breaking it up with a spoon as it cooks.
Allow the beef to sear and form a crispy texture before stirring. Season with salt and pepper as desired.
In a separate skillet, heat a teaspoon of olive oil over medium heat. Add minced garlic (from 2 cloves) and sauté briefly until fragrant.
Add the kale to the garlic and oil, stirring until the leaves wilt but remain bright green, about 3-4 minutes. Season lightly with salt and pepper.
Once all components are cooked, plate the crispy ground beef alongside the roasted sweet potato cubes and garlicky kale.
Serve immediately and enjoy your balanced, flavorful meal.
