Ingredients Method Notes

Ingredients
  

  • - 2 cups cooked chicken breast finely diced or shredded
  • - ¼ cup plain Greek yogurt
  • - ¼ cup olive-oil mayonnaise
  • - 1 tsp extra virgin olive oil
  • - 1 tsp fresh lemon juice
  • - ½ tsp Dijon mustard optional
  • - 1 tbsp fresh dill finely chopped
  • - 1 tbsp green scallions or chives finely chopped
  • - 1 small celery stalk finely diced
  • - Salt and freshly cracked black pepper to taste
  • - 2 large bakery-style croissants sliced horizontally
  • - 4 large green leaf lettuce leaves washed and dried
  • - 1 medium yellow or heirloom tomato sliced into rounds

Method
 

  1. In a medium mixing bowl, whisk together the plain Greek yogurt, olive-oil mayonnaise, extra virgin olive oil, fresh lemon juice, and Dijon mustard until smooth.
  2. Add the diced cooked chicken breast, finely diced celery, chopped fresh dill, and minced scallions to the bowl.
  3. Season with salt and black pepper to taste. Gently fold the chicken mixture until completely coated in dressing.
  4. (Optional) Lightly toast the sliced croissants in an oven at 350°F (175°C) for 2 minutes to crisp the inner crust.
  5. Place 2 green leaf lettuce leaves on the bottom half of each sliced croissant.
  6. Layer sliced yellow/heirloom tomato rounds evenly over the lettuce bed.
  7. Spoon a generous mound of creamy chicken salad filling over the tomatoes.
  8. Place top croissant halves over filling and serve immediately.

Notes

- For meal prep, store chicken salad mixture separately in an airtight container for up to 3-4 days. Assemble sandwiches just prior to eating.
- Rotisserie chicken works exceptionally well and speeds up prep time.
