In a blender or small processor, combine the chopped onion, 1 tbsp garlic, fresh oregano, 2 tbsp olive oil, wine, lemon juice, harissa powder, and black pepper. Pulse until well combined into a coarse paste.
1/2 small onion, 1 tablespoon fresh garlic, 2 tablespoons fresh oregano leaves, 2 tablespoons extra virgin olive oil, 1/4 cup white wine, 1/4 cup freshly squeezed lemon juice, 1 teaspoon harissa powder
In a large roasting pan or rimmed baking sheet, toss the sliced carrots, cherry tomatoes, sliced red onion, olives, and capers with 1-2 tablespoons of the marinade and a pinch of salt and freshly ground black pepper. Spread them out to create a "bed" for the fish.
3 medium carrots, 10 ounces grape , 1/2 medium red onion, 1/2 cup smoked kalamata olives, 2 tablespoons capers, 1/2 teaspoon freshly ground black pepper
Season the butterflied branzino inside and out with salt and pepper. Lay the fish open, skin side down and add a generous amount of the marinade. Spread a generous layer of the Swiss chard and add 1 ounce of the cheese, then fold the fish over. Pour the remaining harissa-oregano marinade over the top of the fish.
1 teaspoon freshly ground black pepper, 2 pounds whole branzino fish, 2 teaspoons kosher salt, Cooled Swiss Chard Stuffing, 2 ounces sheep or goat cheese
Roast in a preheated oven (typically 400°F / 200°C) for 15–20 minutes, or until the fish is opaque and flakes easily with a fork and the vegetables are tender.
