This shrimp piri piri, courtesy of Marcus Samuelsson, is a wonderful appetizer and can be found in Marcus's cookbook, "The Soul of New Cuisine."
Toss shrimp and 1/2 cup piri piri in a large bowl until well combined. Let marinate 20 minutes in refrigerator.
Heat olive oil in a large skillet over medium heat. Add shrimp and cook until opaque throughout, about 2 minutes per side. Transfer shrimp to a plate, sprinkle with salt, and squeeze lime over shrimp.
Spread 1/2 teaspoon remaining piri piri sauce on each lettuce leaf. Top with a shrimp and fold over bottom and sides to form a wrap. Serve immediately.
