Season the chicken breast with half of the sea salt and black pepper.
Heat the olive oil in a large skillet over medium heat and sear the chicken breast for 6-7 minutes per side until fully cooked.
Remove the chicken from the pan, let it rest for 5 minutes, then dice it into bite-sized pieces.
In the same skillet, add the finely diced yellow onion and minced garlic, sautéing for 2-3 minutes until translucent.
Stir in the cooked jasmine rice and frozen green peas, tossing frequently to incorporate the pan juices and heat the peas through.
Add the lemon juice, lemon zest, fresh chopped parsley, and fresh dill to the rice mixture.
Fold the diced chicken back into the skillet, season with the remaining sea salt and black pepper, and serve immediately.
