Heat the olive oil in a frying pan over medium heat.
Add first the bell peppers and cook for 2 minutes, then add onions and cook stirring constantly for 3-4 minutes or until the vegetables are lightly soft.
Add tomatoes, garlic, bay leaves, and oregano. Season with salt and pepper and cook for 2 minutes over medium-low heat.
Stir in in the tomato sauce, then pour 1 ½ cups of water. Bring to a gentle simmer.
Cover and cook for 10 minutes or until the vegetables are cooked through and the sauce has been thickened a bit.
Mix in the olives, capers, and chili peppers. Cook for 1 minute.
Carefully add the fish fillets to the pan, and spoon the flavorful sauce over.
Cook for 4-5 minutes or until fish is nicely cooked through.
Adjust seasonings to taste, turn off the heat, and serve.
Notes
drain the olives and capers well so the sauce stays balanced.
don’t overcook the fish, it only needs a few minutes.
cod works best because it stays firm in the sauce.
if the sauce feels too sharp, let it simmer a little longer before adding fish.
a splash of stock makes the sauce richer and deeper.
