Cook the Pasta: Begin by bringing a large pot of salted water to a boil. Add 2 cups of rigatoni pasta and cook until al dente, around 10 to 12 minutes.
Drain and Rinse: Once cooked, drain the pasta and rinse under cold water to stop the cooking process.
Prepare Other Ingredients: In a large mixing bowl, combine the drained rigatoni with feta cheese, dried cranberries, red onion, and parsley.
Make the Dressing: In a separate bowl, whisk together olive oil, lemon juice, honey, Dijon mustard, salt, and black pepper until combined.
