Season the chicken breast evenly on both sides with the sea salt, black pepper, and dried oregano.
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and cook for 6-7 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and set it aside to rest for 5 minutes before slicing it into strips.
In the same skillet, add the remaining 0.5 tablespoon of olive oil along with the sliced carrots and zucchini.
Sauté the vegetables for 5-6 minutes until they are tender-crisp, stirring in the minced garlic during the final 60 seconds of cooking.
In a small mixing bowl, whisk together the lemon juice, lemon zest, and chopped fresh parsley to create a bright herb drizzle.
Place the warm cooked white rice in a bowl, top with the sliced chicken and sautéed vegetables, and finish by pouring the lemon-herb drizzle over the entire dish.
