In a small bowl; mix seasoning cube, lemon juice, salt, vegetable oil .
Score fish. With your hands, rub the lemon juice mixture generously on the fish. Set it aside for 10 minutes.
Rub some of the jalapeno and green herb marinade on the skin side of fish only.
Heat your non stick skillet over medium-high heat. Place fish skin side down, then rub the other side of the fish with the jalapeno marinade. With the lid on, let it cook for 5minutes.
Take the lid off and turn the fish so the other side can cook. Baste with more of the marinade. Reduce the heat to low and slice your vegetables.
Take the fish out of the skillet and add the vegetables. Season vegetables with the Aubergine pesto. Cook vegetables for at most 3minutes, making sure they are not overcooked.
Serve with fried ripe plantains and hot sauce.
