I took a picture of the whole pan because the fish falls apart very easily so I didn't want to move it because it would have gotten messed up. I will just warm it up when we eat.
4 (6-ounce) tilapia fillets or other white fish fillets
Salt and freshly ground black pepper
1 small onion, chopped
4 garlic cloves, minced
1 1/2 cups canned crushed tomatoes with juice
1 Anaheim chile, stemmed, seeded and cut into thin strips (I left this out as I used the tomatoes with the chilis already in them)
1 bay leaf
1 teaspoon dried oregano
1/2 cup pitted and halved green olives
1/4 cup capers, drained
In a medium saute pan, heat 1 tablespoon of the olive oil over medium-high heat. Season the fish fillets on both sides with salt and black pepper, to taste. Saute the fillets until they are opaque and just cooked through, about 2 minutes per side. Transfer the fish to a glass baking dish where they fit snugly.
In the same saute pan, heat the remaining 2 tablespoons of olive oil over medium-high heat. Add the onion and garlic and cook until the onion is translucent, about 5 minutes. Add the tomatoes, Anaheim chile, bay leaf and oregano and bring the pan to a boil. Reduce the heat to medium, cover and let the sauce simmer until the chilies soften, about 6 minutes. Uncover the pan, add the olives and capers, and cook until the flavors combine, about 4 minutes. Season the sauce with salt and pepper, to taste.
Pour the sauce over the fish in the baking dish. Bake until the fish is heated through, about 5 minutes. Remove the dish from the oven, discard the bay leaf and serve.
