01 - Bring a large pot of salted water to boil. Cook pasta according to package directions until al dente. Drain thoroughly and rinse under cold running water to stop cooking and cool completely.
02 - In a large mixing bowl, whisk together olive oil, lemon juice, Dijon mustard, minced garlic, chopped parsley, dill, salt, and black pepper until emulsified and well combined.
03 - Add the cooled pasta to the bowl with the dressing. Add halved cherry tomatoes, diced cucumber, diced red bell pepper, and sliced spring onions. Toss gently to coat evenly with the dressing.
04 - Fold in the cottage cheese using a spatula, being careful not to break it up completely. Mix until evenly distributed throughout the salad.
05 - Taste the salad and adjust seasoning with additional lemon juice, salt, or pepper as needed. Refrigerate for at least 15 minutes to allow flavors to meld before serving.
