This Italian pasta salad dressing is simple. I think the best version is a bit creamy, but the important thing is the flavor. So make sure to use high-quality olive oil and vinegar; it will make the difference, I promise! To make an easy Italian dressing for pasta salad or any salad, you need a few simple ingredients like EVOO, red wine vinegar, Italian seasoning, salt, and pepper. Add everything to a small jar. If you want the dressing creamier, you can add mayo. Adding a sweetener like honey or maple syrup will help balance all the flavors. Add the lid tightly and shake to emulsify.
