In a small saucepan, combine the dry jasmine rice, 0.4 cup of the water, 1 tablespoon of the coconut milk, and the sea salt.
Bring the rice to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is absorbed and rice is fluffy.
While the rice cooks, heat the coconut oil in a large skillet or wok over medium heat.
Add the green curry paste to the skillet and sauté for 1 minute until it becomes fragrant and slightly darkened.
Add the sliced chicken breast to the skillet and cook for 3-4 minutes until the outside is browned and no longer pink.
Stir in the remaining 2 tablespoons of coconut milk, the remaining 0.1 cup of water, the fish sauce, and the coconut sugar.
Add the green beans and sliced red bell pepper to the skillet and simmer for 5-7 minutes until the chicken is cooked through and vegetables are tender-crisp.
Remove from the heat, stir in the fresh lime juice, and serve the curry over the coconut rice garnished with fresh cilantro.
