Place the sliced almonds in a small dry skillet over medium heat, tossing frequently until they are golden brown and fragrant.
Cut the chicken breast into bite-sized pieces and season with half of the sea salt and black pepper.
Heat the olive oil in a medium saucepan over medium-high heat and sear the chicken until browned on all sides, then remove and set aside.
In the same pan, sauté the finely diced onion and minced garlic for 2 minutes until translucent.
Add the dry basmati rice to the pan, stirring for 1 minute to lightly toast the grains.
Pour in the chicken broth and lemon juice, bringing the mixture to a boil before reducing to a low simmer.
Cover and cook for 15 minutes, or until the liquid is fully absorbed and the rice is tender.
Remove from heat, stir in the cooked chicken and chopped fresh parsley, and let sit covered for 5 minutes.
Fluff the pilaf with a fork and garnish with the toasted almonds before serving.
