Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Place the broccoli florets, sliced bell peppers, and red onion wedges on the baking sheet; drizzle with half of the avocado oil and season with a pinch of the salt and pepper.
Roast the vegetables for 18-20 minutes, tossing halfway through, until the edges are golden-brown and tender.
While the veggies roast, heat the remaining avocado oil in a large skillet over medium-high heat.
Add the ground turkey to the skillet, using a wooden spoon to break the meat into small crumbles as it browns.
Once the turkey is cooked through and no longer pink, stir in the garlic powder, dried oregano, and the remaining sea salt and black pepper.
Remove the roasted vegetables from the oven and fold them directly into the skillet with the turkey, stirring gently to combine the flavors.
Divide the mixture into bowls and garnish with chopped fresh parsley for a bright, clean finish.
