Preheat your oven to 400°F and line a large baking sheet with parchment paper.
In a medium bowl, toss the broccoli florets, diced red bell pepper, and sliced red onion with 1 tsp of avocado oil and half of the garlic powder, sea salt, and black pepper.
Spread the vegetables in a single layer on the prepared baking sheet and roast for 15-18 minutes until tender and slightly charred at the edges.
While the vegetables are roasting, heat the remaining 1 tsp of avocado oil in a large non-stick skillet over medium-high heat.
Add the ground chicken to the skillet, breaking it into small crumbles with a spatula, and season with the remaining garlic powder, smoked paprika, sea salt, and black pepper.
Let the chicken cook undisturbed for 3-4 minutes to develop a golden, crispy crust before stirring and cooking until fully browned and cooked through.
Remove the roasted vegetables from the oven and add them directly into the skillet with the crispy chicken.
Toss everything together for 1 minute to combine the flavors, then serve warm topped with a sprinkle of grated parmesan cheese.
