01 - Bring a small pot of salted water to a boil. Add the shrimp and cook for 2–3 minutes until pink and opaque. Drain and immediately rinse under cold water to halt cooking. Pat dry with paper towels and roughly chop if desired.
02 - In a large mixing bowl, combine the cottage cheese, diced cucumber, red bell pepper, green onions, and chopped basil.
03 - Add the lemon zest and juice, olive oil, sea salt, black pepper, and red pepper flakes if using. Gently fold everything together until well combined.
04 - Add the cooked shrimp to the bowl and fold gently until evenly distributed throughout the salad. Taste and adjust seasoning as needed.
05 - Arrange the butter lettuce leaves on a serving platter. Spoon the shrimp salad evenly into each cup.
06 - Garnish with additional fresh basil or lemon wedges if desired. Serve immediately.
