Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Mince the garlic cloves and dice the red bell pepper into bite-sized pieces.
Cut the chicken breast into even 1-inch cubes to ensure uniform cooking.
In a large mixing bowl, combine the chicken cubes, ground beef, broccoli florets, and bell peppers.
Drizzle the extra virgin olive oil over the mixture and add the minced garlic, oregano, thyme, sea salt, and black pepper.
Toss all ingredients together until the meat and vegetables are thoroughly and evenly coated with the oil and spices.
Spread the mixture in a single layer on the prepared baking sheet, breaking the ground beef into small, bite-sized chunks.
Roast in the center of the oven for 15 to 18 minutes, or until the chicken is cooked through and the beef is nicely browned.
Remove from the oven and let rest for 2 minutes before serving to allow the juices to redistribute.
