Cut fish fillets into 2 or 3 pieces if big. Place in a mixing bowl and rinse with vinegar or lemon and water. Rinse again and drain.

Cut up all vegetables and seasonings.

Add all above seasonings except butter. Mix well in bowl and marinade at least 2 hours.

When ready to cook, heat a large non-stick skillet on medium heat. Add butter to slowly melt.

Place fish in a single layer if possible with all seasonings in bowl on top. Cover pan and cook about 4 minutes, gently turn each piece with a big spoon to cook on the other side another 4 minutes approximately until cooked.

Remove from heat and serve with rice or side of choice. There should be a moderate amount of liquid in the pan, if not add a little water or more butter.
