I too recently came across iceberg again and feel it is underrated. It is a refreshing lettuce that doesn't push its opinions on anyone. Does it need to be in every salad? No, of course not. But it deserves a place in the minor canons https://twitter.com/carney/status/1252815970130735105

You always feel arugula will ask you where you went to school, and romaine is busy climbing the ranks at work, and butter leaf is too busy leading a louche and busy life, but iceberg will just accept your as you are

with your typos and your scars and your flaws and everything
