Wipe the chicken fillets dry with paper towels.
In a wide frying pan, pour in a tablespoon of oil and swirl to coat the entire bottom.
Heat the oil and, when hot, arrange the chicken thigh fillets, skin side down, in a single layer.
Cook the chicken for two to three minutes or until the skins are lightly browned.
Flip the chicken over and allow the opposite sides to brown lightly for about a minute.
Sprinkle the garlic over the chicken.
Pour in the soy sauce and liquid seasoning.
Cover the pan, set the heat to low and braise the chicken for ten minutes or until done and the sauce has reduced to half.
Drizzle the lime juice directly on the chicken fillets and cook for another minute.
Taste and adjust the amount of soy sauce or lime juice, or both, if needed.
Transfer the chicken and sauce to a bowl.
Wipe the pan, pour in the remaining tablespoon of oil and heat.
Throw the onion rings into the oil and cook for about two minutes, stirring often, just until softened.
To serve, ladle rice in four bowls, arrange the chicken thigh fillets over the rice in each bowl (you may want to slice the chicken before serving), drizzle sauce over them, top with onion slices and, optionally, scallions and fried shallots.
