In a small dry skillet over medium heat, toast the sliced almonds until golden and fragrant, then set aside.
Dice the chicken breast into bite-sized pieces and season with 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 from the pan.
Add the finely diced onion to the same pan and sauté until translucent, then stir in the minced garlic and dry basmati rice to toast for one minute.
Pour in the chicken broth, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is absorbed.
Return the chicken to the pan, cover for another 2 minutes to heat through, then fluff the rice with a fork.
Stir in the lemon juice, chopped fresh parsley, and toasted almonds before serving warm.
