01 - Preheat oven to 400°F. Rub chicken breasts with olive oil, salt, and pepper. Place on a baking tray and roast for 15 minutes or until cooked through. Let cool, then dice into small cubes.
02 - In a food processor, combine basil, parsley, pine nuts, garlic, Parmesan, olive oil, lemon juice, and salt. Pulse until smooth but slightly textured.
03 - In a large bowl, combine diced chicken, cottage cheese, cucumber, red bell pepper, green onions, chives, and black pepper. Add 3–4 tablespoons of pesto and gently mix until everything is well coated. Taste and adjust seasoning or add more pesto if desired.
04 - Spoon the chicken salad mixture evenly into the lettuce leaves to form cups. Garnish with extra fresh herbs if desired.
05 - Serve immediately as a light appetizer or lunch.
