In a pot, heat up the oil. Cook the onions, garlic, and ginger for 2-3 minutes or so. Add the chicken pieces to brown. Add the rice, and enough water to cover the chicken. Stir in salt and pepper. Use fish sauce instead of salt if you have any. Cover the pot and let that boil until the rice forms a thick, porridge like consistency. Stir occasionally. Add more water if necessary and adjust the seasonings to your taste.
