Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Place the broccoli florets, chopped red bell pepper, and sliced zucchini on the baking sheet.
Drizzle the vegetables with 1 teaspoon of olive oil and sprinkle with a pinch of sea salt and black pepper, tossing to coat evenly.
Roast the vegetables in the oven for 15 to 20 minutes until they are tender and show slight caramelization on the edges.
While the vegetables roast, heat the remaining 1 teaspoon of olive oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it into small crumbles with a wooden spoon or spatula.
Season the beef with garlic powder, onion powder, sea salt, and black pepper, cooking until it is completely browned and no pink remains.
Drain any excess liquid or rendered fat from the skillet to keep the dish clean and light.
Remove the roasted vegetables from the oven and add them directly into the skillet with the beef.
Toss everything together for 1 minute over low heat to meld the flavors, then garnish with freshly chopped parsley before serving.
