Ingredients
  

  • 12 oz rotini pasta
  • 4 oz Genoa salami, halved or quartered
  • 4 oz provolone cheese, cubed
  • 1 cup cherry tomatoes, halved
  • 1/2 cup black olives, sliced
  • 1/3 cup pepperoncini peppers, sliced
  • 1/2 cup red onion, thinly sliced
  • 1/2 cup roasted red peppers, sliced
  • 1/2 cup Italian dressing
  • 3 tbsp red wine vinegar
  • 1 tsp dried Italian seasoning
  • 1/2 tsp garlic powder
  • Salt and black pepper to taste
  • 2 tbsp grated Parmesan

Method
 

  1. Boil the 12 oz rotini in well-salted water for 1 minute less than the package's al dente time, about 8 minutes. Drain and let it cool for 5 minutes on a sheet pan; it should be slightly warm, not hot.
  2. Whisk together the 1/2 cup Italian dressing, 3 tbsp red wine vinegar, 1 tsp Italian seasoning, and 1/2 tsp garlic powder in a small bowl until combined.
  3. Toss the warm pasta with two-thirds of the dressing in a large bowl. Let it sit for 5 minutes so the pasta absorbs the dressing.
  4. Add the 4 oz salami, 4 oz provolone, 1 cup cherry tomatoes, 1/2 cup black olives, 1/3 cup pepperoncini, 1/2 cup red onion, and 1/2 cup roasted red peppers. Pour the remaining dressing over the top and fold everything together. Taste and season with salt and black pepper.
  5. Cover and refrigerate for at least 1 hour. Before serving, stir well, add a splash of dressing if it looks dry, then transfer to a serving bowl and top with the 2 tbsp grated Parmesan, extra pepperoncini slices, and cracked black pepper.

Notes

This salad is forgiving and flexible, but the two-stage dressing method makes a real difference in the final texture, so don't skip it. If you're making it more than a few hours ahead, hold back a full 2 tbsp of dressing to stir in right before serving. The red onion can be soaked in cold water for 5 minutes before adding if you want a milder flavor.
