Creamy chicken salad on a buttery croissant creates a high protein, elegant lunch that's effortlessly delicious. This family-friendly sandwich is perfect for brunch, picnics, and quick meals.
Dice cooked chicken breast into bite-sized pieces for uniform texture.
Finely chop celery, grapes, and green onion; fold all into the chicken, mixing gently to avoid crushing the grapes.
In a separate bowl, whisk together mayonnaise, Dijon mustard, lemon juice, salt, and black pepper until smooth.
Add the seasoning mixture to the chicken salad, stirring until every component is evenly coated and creamy.
Split croissants in half horizontally; spoon a generous portion of chicken salad onto each base, then top with the croissant lid and serve immediately.
