This is yet another simple and delicious summer salad that is sure to please everyone. I buy refrigerated or fresh cheese tortellini and make my own or I buy basil pesto. I cook the tortellini al dente (do not overcook), add the pesto, then add fresh arugula (one bag) and fresh cherry tomatoes (halve them), add 1 tablespoon of balsamic vinegar, and feta and/or fresh parmesan. I gently combine all the ingredients only turning the salad twice (otherwise it is liable to become mushy). I like to refrigerate it for a couple of hours before serving (although it also tastes good at room temp.).
