Lightly salt and pepper the chicken and brown in a medium saucepan (We're not cooking it all the way through here, just browning it ever so slightly for presentation)
Whisk together 1 ¼ c water, fish sauce, sugar, lime juice, soy sauce, and vinegar. Set aside
In a large saucepan, heat the coconut oil. Add garlic and ginger and sauté until fragrant (~ 30 sec - 1 min)
Add the peppers and cook until they're soft (~ 1 min)
Add the bell pepper & sauté another minute or two
Stir in the fish sauce and raise the heat to high. When it's just on the verge of boiling, add the chicken and stir to mix
Reduce the heat to low and simmer until the chicken has finished cooking through (~ 10 minutes or so)
Serve with coconut rice, spooning the chicken and its sauce over the rice. Garnish with cilantro.
