Creating Greek Yogurt Chicken Salad Lettuce Cups is simple. Just follow these easy steps:

1. Cook Chicken: If you haven’t already, cook chicken breasts by boiling or grilling until fully cooked. Shred or dice the chicken into bite-sized pieces.
2. Mix Ingredients: In a large mixing bowl, combine the shredded chicken, Greek yogurt, diced celery, diced grapes, chopped red onion, Dijon mustard, apple cider vinegar, and dill if using.
3. Season: Season the mixture with salt and pepper to taste. Mix well until all ingredients are thoroughly combined.
4. Prepare Lettuce: Wash and dry the lettuce leaves. You may want to cut the larger leaves in half to create cups.
5. Assemble: Scoop a generous amount of the chicken salad mixture into each lettuce cup.
6. Serve: You can serve immediately or store the chicken salad mixture in the refrigerator for later use.

This advanced preparation method ensures that your Greek Yogurt Chicken Salad Lettuce Cups taste fresh and vibrant.
