Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the broccoli into uniform bite-sized florets and slice the red bell pepper into one-inch strips.
Mince the garlic cloves finely to ensure the flavor distributes evenly.
In a large mixing bowl, combine the chicken breast, broccoli, and bell peppers.
Drizzle with extra virgin olive oil and add the minced garlic, sea salt, black pepper, and dried oregano.
Toss everything thoroughly until the chicken and vegetables are well-coated with the oil and seasonings.
Spread the mixture in a single layer on the prepared baking sheet, ensuring the chicken pieces are not crowded.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly charred.
Remove from the oven and drizzle fresh lemon juice over the entire tray before serving to brighten the flavors.
