Ingredients
  

Pasta Salad With Italian Dressing
  • 1 lb rotini pasta
  • 16 oz Italian dressing
  • 1 cup cherry tomatoes, halved
  • 1 cup cucumber, diced
  • 1 cup green bell pepper, diced
  • 0.5 cup red onion, diced
  • 0.5 cup black olives, sliced
  • 0.25 cup Parmesan cheese, grated
  • 1 tsp Italian seasoning

Method
 

Cook and cool the pasta
  1. Cook rotini pasta according to package directions, then drain and rinse with cold water to stop the cooking and keep it firm. Spread it out briefly so it cools quickly before mixing.
Build the pasta salad
  1. Combine rotini pasta, cherry tomatoes, cucumber, green bell pepper, red onion, and black olives in a large bowl so the vegetables are evenly distributed.
  2. Add Italian dressing, Parmesan, and Italian seasoning and toss until everything is coated, with vegetables visible and the dressing clinging to the pasta.
Chill and finish
  1. Refrigerate the pasta salad for at least 2 hours so the flavors develop and the salad thickens slightly as it chills. Cover the bowl to prevent drying.
  2. Toss again before serving and add more Italian dressing if needed to loosen and re-coat the pasta evenly.

Notes

For the best texture, rinse the pasta with cold water thoroughly so it doesn’t keep cooking or turn gummy. Refrigerate in a covered container up to 4 days; it’s not recommended to freeze because vegetables and dressing can separate. Dietary swap: use a low-sodium or light Italian dressing to reduce sodium while keeping the same tangy flavor profile.
