This orzo pasta salad recipe, from Giada De Laurentiis, is one of my go-to's and everyone loves it. I use spinach instead of arugula to keep it more kid friendly, feta instead of ricotta salata, craisins instead of dried cherries, and I leave out the pine nuts b/c I have a nut allergy. You can't go wrong.
