Mediterranean Seafood Grill with Skordalia

Ingredients

• 1 pound russet or Yukon gold potatoes, peeled and diced
• 8 garlic cloves, peeled
• 1 slice sourdough bread, crust removed, and torn into pieces
• 1/4 cup plain low-fat Greek yogurt
• 3 tablespoons olive oil, divided
• Zest and juice of 1 lemon
• 1/2 teaspoon salt, divided
• 1/4 teaspoon dried thyme
• 1 pound halibut fillets, cut into 4 pieces
• 2 red bell peppers, quartered
• 1 pound small zucchini, diagonally cut into 1-inch pieces
• 1/2 red onion, sliced

Preparation

1. 1. Place potatoes in a large saucepan, add garlic, cover with cold water, and cook over high heat 15 minutes or until potatoes are tender.
2. 2. While the potatoes cook, place the bread in a large bowl. Spoon 2–3 tablespoons cooking liquid from potatoes over bread. Stir with a fork until smooth. Add yogurt, 2 tablespoons olive oil, and lemon zest and juice; stir until a smooth paste forms.
3. 3. Place a large bowl in the sink, and set a colander on top. Drain potatoes and garlic, reserving cooking liquid. Transfer potatoes to bread mixture, and mash until smooth. Add reserved cooking liquid 2 tablespoons at a time until mixture takes on the consistency of loose mashed potatoes. Stir in 1/4 teaspoon salt and 2 teaspoons olive oil. Cover and keep warm.
4. 4. Preheat grill pan over medium-high heat. Drizzle fish with 1/2 teaspoon olive oil, and sprinkle with remaining 1/4 teaspoon salt and thyme. Cook 2–3 minutes on each side or until fish flakes easily with a fork. Transfer to a plate; cover and keep warm.
5. 5. Place bell pepper, zucchini, and red onion in a large bowl. Drizzle with remaining 1/2 teaspoon olive oil; toss to coat. Arrange bell pepper in grill pan, and cook 5 minutes over medium heat. Add zucchini and onion; cook 10 minutes or until vegetables are tender, turning as necessary for even cooking.
6. 6. Serve halibut with grilled vegetables and skordalia.
