1 pound medium shrimp, with shells
1 onion, chopped
2 tablespoons chopped fresh parsley
1 cup white wine
1 (14.5 ounce) can diced tomatoes, drained
1/4 teaspoon garlic powder (optional)
1/4 cup olive oil
1 (8 ounce) package feta cheese, cubed
salt and pepper to taste
Bring about 2 inches of water to a boil in a large saucepan. Add the shrimp, the water should just cover them. Boil for 5 minutes, then drain, reserving the liquid, and set aside.
Heat about 2 tablespoons of oil in a saucepan. Add the onions; cook and stir until the onions are soft. Mix in the parsley, wine, tomatoes, garlic powder, and remaining olive oil. Simmer, stirring occasionally, for about 30 minutes, or until the sauce is thickened.
While the sauce is simmering, the shrimps should have become cool enough to handle. First remove the legs by pinching them, and then pull off the shells, leaving the head and tail on.
When the sauce is thickened, stir in the shrimp stock and shrimp. Bring to a simmer, and cook for about 5 minutes. Add the feta cheese and remove from the heat. Let stand until the cheese starts to melt. Serve warm.
