Preheat the oven to 425°F.
Wash and dice the sweet potato into bite-sized cubes. Toss with half a teaspoon of olive oil, a pinch of salt, pepper, and garlic powder.
Spread the sweet potato cubes on a baking sheet and roast in the oven for 20-25 minutes until tender and slightly caramelized.
Meanwhile, chop the broccoli into florets, toss with the remaining olive oil, salt, and pepper, and add to the baking sheet during the last 10 minutes of roasting to achieve a crispy texture.
In a skillet over medium heat, add the lean ground beef. Season with salt, pepper, and a pinch of garlic powder. Cook, breaking it up with a spatula, until browned and cooked through, about 6-8 minutes.
Once all components are cooked, layer the roasted sweet potatoes and crispy broccoli on a plate and top with the seasoned ground beef.
Serve immediately and enjoy your nutrient-packed meal.
