Season the chicken breast with the sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken until golden on both sides, then remove and set aside.
In the same skillet, add the diced yellow onion and minced garlic, sautéing until the onion is translucent and fragrant.
Add the basmati rice to the skillet and stir for one minute to lightly toast the grains.
Pour in the chicken bone broth and lemon juice, scraping the bottom of the pan to release any browned bits.
Return the chicken to the skillet, bring the liquid to a boil, then reduce heat to low and cover with a lid.
Simmer for 15 minutes or until the rice is tender and the liquid is absorbed.
Stir in the green peas, lemon zest, and fresh parsley, then cover for 2 more minutes to steam the peas before serving.
