Chef John's Antipasto Pasta Salad
You can use balsamic vinegar for something on the sweeter side, or a combination of both red wine vinegar and balsamic.
You can add a pinch of cayenne to your dressing if you like. You can also use any green chile pepper you like for this salad, as well as any other Italian meats and cheeses you prefer.
Make sure you don't add any meats or cheeses to the still-warm pasta; allow it to cool to room temperature.
