Preheat your oven to 400°F and line a baking sheet with parchment paper.
Slice the zucchini and carrots into bite-sized rounds or half-moons.
Toss the vegetables on the baking sheet with 0.5 tablespoons of olive oil, sea salt, and black pepper.
Roast the vegetables for 15 to 20 minutes until they are tender and show slightly caramelized edges.
While the vegetables roast, cut the chicken breast into small cubes.
Heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Add the chicken cubes and ground beef to the skillet, breaking up the beef with a spatula.
Season the meat with garlic powder and onion powder, then sauté until the chicken is cooked through and the beef is browned.
Stir in the rinsed black beans and the pre-cooked white rice, heating everything together for 2 to 3 minutes.
Divide the rice and meat mixture into a bowl and top with the roasted zucchini and carrots.
