Pour the lime juice over the chicken and let sit while you prepare the rest of the soup.
In a medium saucepan, place the coconut milk, lime peel, ginger and chili peppers. Bring the mixture to a simmer. Add the chicken and stir to distribute them evenly. Reduce the heat so the soup stays just under a boil and let cook for 12-15 minutes or until the chicken is done. Remove from heat and serve immediately with the cilantro on top.
