Manestra is a humble one-pot dish common throughout Greece. At its most simple, it’s just orzo (in Greek called kitharaki) in tomato sauce. You can make that sauce from tomato paste or with canned or fresh tomatoes (wait till they’re in season). But you can also dress it up a bit and make it heartier with a little chicken or other meat. That’s what I’ve done here, because that’s how I remember eating it.
