Rub the chicken breast evenly with the jerk seasoning, sea salt, black pepper, and olive oil.
In a small saucepan, combine the basmati rice, kidney beans, coconut milk, water, minced garlic, and the sprig of thyme.
Bring the rice mixture to a boil over medium-high heat, then reduce to a low simmer and cover with a tight-fitting lid.
Cook the rice for 15 to 18 minutes until the liquid is fully absorbed and the grains are tender.
While the rice cooks, preheat a grill pan or cast-iron skillet over medium-high heat.
Sear the chicken for 6 to 7 minutes per side until a golden-brown crust forms and the internal temperature reaches 165°F.
Remove the thyme sprig from the rice, fluff with a fork, and serve the sliced jerk chicken over the creamy rice and beans.
