Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rub the chicken breast with 0.5 tablespoon of olive oil, sea salt, black pepper, and dried oregano until evenly coated.
Place the chicken on the prepared baking sheet and roast for 20 to 25 minutes, or until the internal temperature reaches 165°F.
While the chicken is roasting, mince the garlic and finely chop the fresh parsley.
Heat the remaining 0.5 tablespoon of olive oil in a small saucepan over medium heat.
Add the minced garlic and sauté for 30 seconds until fragrant, then add the dry rice and stir to toast the grains for 1 minute.
Pour in the chicken broth, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is fully absorbed.
Remove the rice from heat and let it sit covered for 5 minutes before fluffing with a fork.
Stir the fresh lemon juice, lemon zest, and chopped parsley into the rice pilaf to combine.
Slice the roasted chicken into thin strips and serve immediately over the warm, fragrant rice.
