Apply Knorr Liquid Seasoning all over the tilapia. Let it stand for 10 minutes so that the fish can absorb the flavor of the seasoning.
Heat around 1 cup of cooking oil in a pan. Once the oil gets hot, fry the fish until the color turns golden brown. Flip to fry the opposite side. Remove from the pan. Place on a clean plate. Set aside.
Make the sauce by heating 3 tablespoons of cooking oil in a cooking pot. Saute onion and garlic for 10 seconds. Add ginger. Saute for 12 seconds.
Pour white vinegar and water. Let boil.
Add tomato ketchup. Stir until it completely dilutes in the mixture.
Add sugar. Stir until the sugar gets fully incorporated.
Put carrots and bell peppers. Cook for 3 minutes.
Combine cornstarch and 3 tablespoons water. Mix well. Pour into the cooking pot. Stir until sauce thickens.
Season with salt and ground black pepper. Add a piece of tilapia and cook for 3 minutes.
