Bring a large pot of salted water to a boil. Add pasta and cook according to package directions for al dente. Drain and rinse under cold water to stop cooking. Set aside.

In a blender or food processor, combine cottage cheese, Greek yogurt, lemon juice, olive oil, garlic, herbs, and a pinch of salt. Blend until smooth and creamy. Taste and adjust salt, pepper, or lemon.

In a large bowl, combine cooled pasta, cherry tomatoes, cucumber, red onion, and protein choice. Pour dressing over and toss until everything is evenly coated.

Refrigerate for 20–30 minutes to let flavors marry, or serve immediately at room temperature.
