This pasta salad style orzo recipe is a great thing to bring to a BBQ or picnic. Its so popular at my house that I have to set some aside if I want any leftovers. The roasted bell peppers and eggplant give it a colorful look, and the sesame oil adds a delicious and unusual flavor. It serves as an excellent side to BBQ chicken or steak. I usually roast the vegetables in the oven, but feel free to roast them on the BBQ in larger slices and then chop to bite-size once cooked.
