Place the shredded chicken in a medium mixing bowl.
In a separate small bowl, whisk together the Greek yogurt, lemon juice, Dijon mustard, and garlic powder until smooth. Season this dressing with salt and pepper.
Pour the dressing over the shredded chicken.
Add the chopped celery and red onion. If using optional additions like grapes or walnuts, add them now.
Gently fold all ingredients together until the chicken is evenly coated. Do not overmix.
Taste the salad and adjust salt, pepper, or lemon juice as needed for your preference.
For best flavor, cover the bowl and chill the salad in the refrigerator for at least 30 minutes before serving. This allows the flavors to combine.
Notes
For a **Vegan Protein Salad**, substitute canned, rinsed, and mashed chickpeas for the chicken and use a vegan mayonnaise or cashew cream base instead of yogurt.
This recipe makes about 4 servings and keeps well for up to 4 days when stored in an airtight container in the refrigerator, making it excellent for **meal prep salads**.
To keep this a **low carb protein salad**, serve the mixture in large lettuce cups or with sliced cucumbers instead of bread or crackers.
