Don't over cook the pasta. You want it to have a nice bite to it.
If making this ahead of time, reserve some of the dressing when you originally make it, and add some fresh dressing right before serving.
Try different shapes of pasta to mix it up.
Make sure all the ingredients are in bite sized pieces for easier serving and eating.
Refrigerated is best, but this can be served at room temperature. Just don't let it sit at room temp for more than 1 hour.
Make sure to use FRESH mozzarella and not the pre-shredded, or block version. They are very different!
Add in baked or grilled chicken to make it a meal!
