Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Season the chicken breast evenly with sea salt, black pepper, and dried oregano.
Roast the chicken for 20 to 25 minutes until the internal temperature reaches 165°F, then let it rest for 5 minutes before slicing.
While the chicken roasts, heat the extra virgin olive oil in a non-stick skillet over medium heat.
Add the diced yellow onion and minced garlic, sautéing until translucent and fragrant.
Fold in the cooked basmati rice and green peas, stirring constantly until the mixture is heated through.
Remove the skillet from the heat and stir in the lemon juice, lemon zest, fresh parsley, and fresh dill.
Slice the rested chicken breast into thin strips and serve immediately over the citrusy herb pilaf.
