Cook chicken breasts seasoned with chicken seasoning or salt until fully cooked and let cool.
Chop the cooked chicken into bite-sized pieces or shred if using rotisserie chicken.
In a large bowl, combine mayonnaise, cottage cheese, lemon juice, dried oregano, garlic powder, smoked paprika, onion powder, black pepper, and salt.
Add chopped celery and quartered grapes to the dressing mixture.
Fold in the chopped chicken gently until well coated.
Taste and adjust seasoning or mayonnaise to your preference.
Serve chilled on its own, in a wrap, or with crackers and fresh fruit.
Store leftovers in an airtight container in the refrigerator for up to 3 days.
