Creating this delightful Shrimp Salad on Croissants can be straightforward if you follow these steps:

1. Prepare the Shrimp: In a pot of boiling salted water, cook the shrimp until pink and opaque, about 3-4 minutes. Drain and let cool.
2. Mix Sauce: In a large bowl, combine mayonnaise, sour cream, Dijon mustard, lemon juice, dill, and chives.
3. Seasoning: Add salt and pepper to the mixture, adjusting to your taste.
4. Combine Shrimp and Sauce: Once shrimp are cool, chop them into bite-sized pieces. Gently fold the shrimp into the sauce until well combined.
5. Prepare Croissants: Slice croissants in half without cutting all the way through. Open them up, creating pockets for the salad.
6. Assemble: Place a layer of lettuce leaves inside each croissant. Spoon the shrimp salad generously into each croissant.
7. Optional Addition: If desired, add sliced tomatoes for an extra flavor boost.
8. Serve: Enjoy immediately or refrigerate for later use.
