What can I call this side dish (I have to write it on a restaurant menu)?
I have already written "cooked swiss chard" but I think it is not the exact definition. It is a mix of herbs that grow spontaneously on the fields, are then cooked and sautéed in a pan with oil, garlic and chilli. In Italian they are called "field herbs".
