Butterflied shrimp are dipped in flour and egg, then pan-seared until browned on the outside and tender and juicy inside. A quick, buttery white wine sauce and wilted baby spinach complete this easy, elegant dish.
Butterfly the shrimp: Make a deep cut along the outer curved edge of a shrimp, then spread open like a book. Repeat with the remaining shrimp. Pat dry.
Whisk the eggs with 1 teaspoon salt, 1/2 teaspoon pepper and 1 tablespoon parsley in a bowl. Heat about 1/8 inch olive oil in a large skillet over medium-high heat. Put the flour in a shallow bowl. Working in batches, dredge the shrimp in the flour, dip in the egg mixture and add to the skillet cut-side down; fry, turning, until lightly browned, about 3 minutes. Transfer to paper towels to drain.
Pour out any oil from the skillet and wipe clean. Add the broth, wine and lemon juice and bring to a boil over medium-high heat. Add the tomatoes and cook until the sauce is slightly reduced, about 4 minutes. Push the tomatoes to one side; whisk in the butter a few pieces at a time. Stir in the shrimp and the remaining 1 tablespoon parsley.
Meanwhile, put the spinach in a microwave-safe bowl, sprinkle with water and season with salt and pepper. Cover with plastic wrap and pierce the plastic; microwave until wilted, 3 to 5 minutes. Divide the spinach and shrimp mixture among plates and top with the sauce.
