Cook the Pasta: Begin by boiling a pot of salted water. Add the bowtie pasta and cook according to the package instructions until al dente. Drain and let it cool for a few minutes.
Prepare the Veggies: While the pasta is cooling, thinly slice the red onion, dice the cucumber, and halve the cherry tomatoes. If you’re using arugula or spinach, give them a quick rinse and let them dry.
Combine Ingredients: In a large mixing bowl, combine the cooled pasta, red onion, arugula or spinach, olives, cherry tomatoes, and cucumber.
Add Dressing: Pour in the creamy dressing over the pasta and veggies. Gently toss everything together until well coated.
Season: Add salt and pepper to taste, adjusting as needed.
Chill and Serve: For the best flavors, let the salad chill in the refrigerator for about 30 minutes before serving.
