Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Slice the zucchini into very thin rounds, approximately 1/8-inch thick, to ensure they become crisp like chips.
Cut the chicken breast into thin, bite-sized strips so they cook quickly alongside the zucchini.
In a small bowl, whisk together the olive oil, lemon juice, lemon zest, dried oregano, garlic powder, sea salt, and black pepper.
Place the chicken and zucchini rounds on the prepared baking sheet in a single layer, ensuring they do not overlap.
Drizzle the lemon-herb mixture over the chicken and zucchini, tossing gently with your hands to coat every piece evenly.
Roast in the oven for 15-18 minutes, or until the chicken is cooked through and the zucchini chips are golden and slightly crisp.
Remove from the oven and garnish with freshly chopped parsley before serving immediately.
