Creating this scrumptious Shrimp Salad on Croissants is straightforward if you follow these clear steps:

1. Cook the Shrimp: In a medium pot, bring salted water to a boil. Add the shrimp and cook until they are pink and opaque, about 2-3 minutes. Drain and cool.
2. Prep the Ingredients: Once the shrimp are cool, chop them into bite-sized pieces.
3. Mix the Dressing: In a bowl, combine the mayonnaise, Dijon mustard, lemon juice, garlic powder, salt, and pepper. Stir well until smooth.
4. Combine Shrimp and Veggies: In a large bowl, add the chopped shrimp, celery, and red onion. Pour the dressing over the mixture and fold gently to combine.
5. Chill the Salad: Cover the bowl with plastic wrap and refrigerate for 10-15 minutes to allow the flavors to meld.
6. Prepare the Croissants: While the salad chills, slice the croissants in half horizontally.
7. Assemble: Fill each croissant with a generous serving of the shrimp salad. Add lettuce if desired for extra crunch.
8. Serve: Arrange the croissants on a platter and serve immediately for the best taste.
