How to Make Chicken Salad Croissant Sandwiches

Step 1 – Cook and Shred the Chicken
Boil chicken breasts in a pot of water until fully cooked.

Let cool slightly, then shred into bite-sized pieces.

Step 2 – Mix the Dressing
In a large bowl, combine mayonnaise, apple cider vinegar, salt, and pepper.

Stir well to create a smooth dressing.

Step 3 – Add the Fillings
Add shredded chicken, halved grapes, chopped red onion, sliced green onions, and chopped water chestnuts into the bowl.

Gently fold everything together until evenly coated.

Step 4 – Chill
Cover and refrigerate the salad for at least 1 hour.

This helps the flavors meld beautifully.

Step 5 – Assemble the Sandwiches
Slice croissants in half lengthwise.

Spoon a generous portion of chilled chicken salad onto the bottom half, then top with the other half of the croissant.

Serve immediately.
