Prepare the jasmine rice according to package instructions and set aside.
Slice the chicken breast into thin, bite-sized strips and season lightly with sea salt.
Heat the coconut oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sear until golden on all sides, then remove and set aside.
In the same skillet, add the green curry paste and stir for 1 minute until fragrant.
Whisk in the coconut milk and water, bringing the mixture to a gentle simmer.
Add the green beans and sliced red bell pepper to the sauce, simmering for 4 minutes.
Return the chicken to the skillet and continue to simmer until the vegetables are tender-crisp and chicken is cooked through.
Stir in the fish sauce, lime juice, and fresh Thai basil leaves just before serving.
Serve the curry hot over the prepared jasmine rice.
