Preheat oven to 400°F and line a large baking sheet with parchment paper.
Dice the sweet potatoes into 1-inch cubes and toss with 1 tablespoon of olive oil, sea salt, and black pepper.
Season the chicken breast with garlic powder, sea salt, and black pepper, then place on the baking sheet with the potatoes.
Roast for 25-30 minutes until the chicken is cooked through and the potatoes are golden and tender.
While roasting, steam the broccoli florets until vibrant green and slightly tender.
In a small bowl, whisk together the remaining olive oil, lime juice, and honey to create a dressing.
Assemble the platter by layering the cooked quinoa, black beans, roasted potatoes, steamed broccoli, and sliced chicken.
Top with sliced avocado and drizzle the honey-lime dressing over the entire dish.
