Wash the rice well under cold water, then place in a saucepan with water to cover by 1/4". Bring to a boil over high heat, then turn the heat down low and cover tightly. Simmer until all water is absorbed, approximately 1 hour. In a frying pan or wok, heat the oil and saute the onions until golden brown or even a bit burnt, about 8 minutes. Add the cooked rice to the onions. Stir in the carrots, sesame seeds, salt and pepper to taste, and the herbs. Stir-fry lightly for about 5 minutes. Mix in the soy sauce just before serving, if desired.
