Orzo with Roasted Vegetables

For some reason I couldn't find orzo at the store (maybe I was blind), so I substituted acini di pepe which is an adorable little pasta.  It seemed a little oily to me, so I might cut back on the oil next time.  Other than that, the only other major change I made was eating it while it was still warm instead of letting it cool.
