Place the sliced almonds in a dry skillet over medium-low heat and toast for 2-3 minutes until golden and fragrant, then set aside.
Season the chicken breast with half of the sea salt and black pepper.
In a small saucepan, heat the olive oil over medium heat and sauté the diced onion and minced garlic until translucent.
Add the dry basmati rice to the saucepan and stir for 1 minute to lightly toast the grains.
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.
While the rice cooks, heat a non-stick skillet over medium-high heat and sear the chicken breast for 5-7 minutes per side until fully cooked through.
Once the rice is done, fluff it with a fork and stir in the lemon juice, lemon zest, fresh parsley, fresh dill, and the remaining salt and pepper.
Slice the chicken breast and serve it over the rice pilaf, garnishing the entire dish with the toasted almonds.
