Pickled lettuce

I've just seen a comment on a local site saying he'd pickled his lettuce - has anyone pickled their lettuce before? I haven't got a jar big enough for my lettuces.  BTW the cosberg lettuces I've grown this year are very nice.

Was it a typo for "picked"??

I read about BBQ's lettuce the other day - Riverford, I think.

No not a typo, the chappie says it's nice made with garlic, chilli and dill.  I've  asked him to post the recipe.  He says he cuts his lettuce up before pickling.
