Follow these simple steps to make your refreshing Cucumber Pasta Salad:

1. Cook Pasta: Bring a large pot of salted water to a boil. Add the rotini or fusilli pasta and cook according to package instructions until al dente.
2. Drain and Cool: Once cooked, drain the pasta in a colander and rinse under cold water to stop the cooking process. Set aside to cool completely.
3. Prepare Vegetables: While the pasta cools, chop the cucumber, halved cherry tomatoes, diced bell pepper, and finely chopped red onion.
4. Mix Dressing: In a small bowl, whisk together the olive oil, apple cider vinegar, Dijon mustard, garlic powder, and a pinch of salt and pepper to create the dressing.
5. Combine Ingredients: In a large mixing bowl, combine the cooled pasta, diced cucumber, cherry tomatoes, red onion, bell pepper, crumbled feta cheese, and chopped parsley.
6. Add Dressing: Pour the dressing over the pasta and vegetables. Toss gently to combine, ensuring everything is coated.
7. Chill: Cover the bowl with plastic wrap or a lid and place in the refrigerator for at least 30 minutes to allow the flavors to meld.
8. Taste and Adjust: Before serving, taste the salad and adjust seasoning with more salt or pepper if desired.
