01 - Place eggs in a saucepan and cover with cold water. Bring to a boil, then reduce heat and simmer for 10 minutes. Drain and cool eggs under cold running water until safe to handle.
02 - Peel the cooled eggs and chop into bite-sized pieces. Set aside for assembly.
03 - In a large mixing bowl, combine cottage cheese, Dijon mustard, lemon juice, salt, and pepper. Stir vigorously until mixture reaches a smooth, creamy consistency.
04 - Add chopped eggs, celery, red onion, chives (or green onions), and parsley to the bowl. Gently fold together using a spatula, ensuring eggs remain chunky and ingredients are evenly distributed.
05 - Taste the salad and adjust salt or pepper as needed. If desired, sprinkle smoked paprika over the top as a garnish before serving.
06 - Serve chilled on whole-grain toast, in lettuce cups, or as a sandwich filling. For added flavor, consider adding capers or chopped dill pickles.
