Preheat the oven to 350°F (175°C).
Spread the sliced almonds evenly on a rimmed baking sheet.
Bake for about 5 minutes, or until lightly golden and fragrant.
Remove from the oven and allow the almonds to cool for 5–10 minutes.
In a large mixing bowl, combine the chicken, celery, scallions, parsley, Greek yogurt, Dijon mustard, black pepper, olives, cranberries, sea salt, and lemon juice.
Add the cooled toasted almonds.
Stir until everything is evenly combined.
Taste and adjust the seasoning with additional salt or lemon juice if desired.
