Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch bite-sized pieces and slice the baby potatoes into halves or quarters to ensure they cook at the same rate as the chicken.
Chop the broccoli florets, bell peppers, and zucchini into uniform pieces.
In a small bowl, whisk together the extra virgin olive oil, fresh lemon juice, dried oregano, garlic powder, sea salt, and black pepper.
Place the chicken and all the chopped vegetables onto the prepared sheet pan.
Drizzle the lemon-herb mixture over the ingredients and toss thoroughly with your hands or tongs until everything is evenly coated.
Spread the mixture into a single layer and roast for 20-25 minutes, or until the chicken is cooked through and the potatoes are fork-tender and golden.
Garnish with fresh chopped parsley and an extra squeeze of lemon before serving or portioning into meal prep containers for the week.
