Preheat your oven to 400°F (200°C).
Pat the chicken breast dry with a paper towel and rub with 0.25 tbsp of the olive oil, dried oregano, sea salt, and black pepper.
Place the chicken in a small baking dish, top with thin slices from the half lemon, and roast for 20-25 minutes until the internal temperature reaches 165°F.
While the chicken roasts, heat the remaining 0.5 tbsp of olive oil in a small saucepan over medium heat and sauté the minced garlic until fragrant.
Add the dry basmati rice to the saucepan, stirring for 1 minute to lightly toast the grains.
Pour in the chicken bone broth, bring to a gentle boil, then cover and reduce heat to low for 15 minutes until the liquid is fully absorbed.
Steam the green beans in a steamer basket over boiling water for 5-7 minutes until they are bright green and crisp-tender.
Fluff the rice with a fork, stir in the chopped fresh parsley, and serve alongside the sliced roasted chicken and steamed beans.
