1. Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package directions until al dente, usually about 9-11 minutes. Drain and rinse under cold water to stop the cooking process and cool the pasta for the salad.
2. While the pasta cooks, prepare the dressing. In a small bowl, whisk together the olive oil, red wine vinegar, honey, Dijon mustard, salt, and pepper until well combined and slightly emulsified. This dressing is the heart of the salad, so taste and adjust the sweetness or acidity as you prefer.
3. In a large mixing bowl, combine the cooled pasta, crumbled feta, dried cranberries, toasted walnuts, parsley, and red onion if using. Toss gently to mix the ingredients evenly.
4. Pour the dressing over the salad and toss again until everything is coated. Be gentle here to keep the feta from breaking down too much.
5. Cover and refrigerate the salad for at least 30 minutes before serving. This resting time lets the flavors marry beautifully—something I learned the hard way when rushing a similar pasta salad years ago. Patience truly pays off!
6. Before serving, give the salad a final toss. Taste and adjust seasoning with more salt, pepper, or vinegar if needed.

I remember the first time I made this salad for a family picnic. I was worried it might be too simple, but it was gone in minutes. Since then, this recipe has become my go-to for occasions where I want to impress without stress—a reminder that sometimes, the simplest recipes create the most lasting memories.
