Hello, Craig, I don't know if this would work with your NZ spinach, but a way we love to use spinach is to saute some onions garlic and diced prosciutto in olive oil, then prepare a simple bechamel sauce. Put into the sauce spinach which has been steamed in its own water, then pressed to get rid of most of it, and heat it in the bechamel sauce for a few minutes, then serve over pasta. It's wonderful with a grind or two of pecarino romano or pecarino tuscarello. Give a shout if you would like the actual recipe. Ron
