Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into half-inch cubes, then toss them with half of the avocado oil and a pinch of sea salt.
Spread the sweet potatoes in a single layer on the baking sheet and roast for 20-25 minutes until they are tender and caramelized.
While the potatoes roast, heat the remaining avocado oil in a large skillet over medium-high heat.
Add the ground chicken to the skillet, breaking it apart with a spatula, and season with sea salt, black pepper, dried oregano, and onion powder.
Cook the chicken until it is thoroughly browned and cooked through, stirring in the minced garlic during the final 2 minutes of sautéing.
Steam the broccoli florets in a steamer basket over boiling water for approximately 4-5 minutes until they are bright green and just fork-tender.
Assemble the bowl by layering the roasted sweet potatoes, savory ground chicken, and steamed broccoli together.
Top the bowl with hemp hearts for a nutty crunch and serve immediately while hot.
