Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Dice the red bell pepper and red onion into bite-sized pieces, and slice the zucchini into half-moons.
In a large bowl, toss the prepared vegetables with the extra virgin olive oil, half of the garlic powder, half of the smoked paprika, and a pinch of sea salt and black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 18-20 minutes until tender and slightly caramelized at the edges.
While the vegetables roast, heat a large non-stick skillet over medium-high heat.
Add the ground beef to the skillet, breaking it up with a wooden spoon as it cooks.
Season the beef with the remaining garlic powder, smoked paprika, sea salt, and black pepper.
Cook the beef for 7-8 minutes until fully browned and cooked through, then drain any excess fat if necessary.
Plate the savory ground beef alongside the roasted vegetables and serve immediately.
