Have you heard or rapini? It gets called broccoli raab or rabe too and you can usually find it at green grocers or farmer’s markets. I’ve never seen it at a big supermarket in Melbourne but if you have, let me know. It’s part of both the cabbage and turnip  families and used in Italian cooking. I love it as it’s like spinach with bite. If you can’t find it you could use spinach with a small handful of rocket thrown in for that bit of bite.
