How to make
Sprinkle the catfish fillets with salt and freshly ground black pepper.
Pour the mixture of soy juice and balsamic vinegar over them and leave them in a bowl for 15 minutes in the refrigerator, by turning them 2-3 times.
Heat the grill and grease it, to prevent the fish from sticking.
Throw the pieces of catfish on the grill and grill them on each side, until an appetizing color is obtained.
The grilled catfish is ready.
