Rinse the oysters in a bowl of lemon water to remove any dirt and fishy taste.
In a mixing bowl, mix the tapioca flour and water for the batter and set aside.
Preheat the frying pan on KITH Smokeless BBQ Grill (Touch Control) SBG-TC-B1, set 280°C for 5 minutes.
Add 2 tablespoon of cooking oil on the frying pan over high heat. Stir fry the batter over the pan to form a layer. Leave it to cook until it is set and turned slightly gooey for about 15 minutes. Add in minced garlic and stir fry for 3 minutes.
Pour the egg mixture over the batter and cook until the omelette is cooked. Make some space in the middle, add in 1 tablespoon of cooking oil and oysters and fry for about 8 minutes. Flip over the omelette occasionally so that it gets a nice brown on both sides.
Serve the omelette and oysters on a plate, garnish with parsley and chilli sauce (optional).
