Dice the chicken breast into bite-sized pieces and season with a pinch of sea salt and black pepper.
Heat the olive oil in a medium saucepan over medium heat, then add the finely chopped yellow onion and minced garlic, sautéing until translucent.
Add the chicken pieces to the pan and cook for 3 to 4 minutes until lightly browned on all sides.
Stir in the dry basmati rice and toast for 1 minute until the grains are slightly translucent at the edges.
Pour in the chicken broth and bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes or until the liquid is absorbed.
Remove from heat and let the pilaf sit covered for 5 minutes to allow the rice to finish steaming.
Fluff the rice with a fork and stir in the lemon juice, lemon zest, chopped parsley, and fresh dill before serving.
