Preheat the oven to 375º F.
Season the fish. Pour the olive oil onto a non-stick baking tray. Sprinkle it with salt, pepper, and oregano. Place the fish fillet(s) on top, and gently rub it into these seasonings. Flip the fish and set aside.
Make the Roasted Pepper Paste. Place all of the paste ingredients into a food processor and pulse until fairly smooth.
Spread the paste onto the fish evenly.
Make the Breadcrumbs. Into the same food processor (no rinsing needed), place the bread together with the garlic and anchovy fillets. Add a little black pepper. Pulse until the breadcrumbs form.
Top the cod with breadcrumbs, and bake for about 20-25 minutes, depending on how thick your cod fillet is.
