Add chicken, celery, onion, Greek yogurt, almonds, mustard, parsley, pepper and salt into a large bowl.
Toss to combine. Taste and add more yogurt, salt and pepper, if needed.
Place salad in an airtight container in the fridge. The salad will keep for 3-5 days.
Notes
I like to eat mine with gluten free crackers but you can also make a sandwich, lettuce wraps, eat in a pita or over greens.If you want a sweeter taste, add honey and/or grapes.I doubled this recipe to have enough for the week! I like to eat a larger portion of this to increase my protein intake at lunch!
