Cut a large sheet of aluminium foil (bigger than your pan) and put it in the bottom of the baking pan, leaving enough of the aluminium foil to cover the fillets on top.
Finley chop bell pepper, tomatoes, onion, garlic and fresh cilantro.
In a mixing bowl, mix all the ingredients except for the sea bass fillets.
Place the fish filets on the foil paper, and sprinkle them with e salt and cumin.
Now, top the fish filets with the veggie mix and press lightly, then fold the foil pepper on top of the fish.
Bake for 25-30 minutes. Serve warm.
Notes
Use any other kind of fish you like if you can't find the sea bass.
