Funny you should ask this. I gave lettuce up a few months back, its just tasteless to me now. I replaced it with watercress that has a lot more taste and you don't end up throwing any away like you do lettuce.
I occasionally buy Butterhead lettuce in little bags - more tasty than the bog standard stuff. Nice when having steak and chips with a few vine tomatoes and pickled onions.
//....offers a broken surface in each leaf which will retain any salad dressing.//
The easy way to avoid that problem is not to put any salad dressing on in the first place. It's ghastly stuff (in all its various incarnations) which, if you are unfortunate enough to be landed with any, is best used to clean the grease off car windscreens. Some of the thicker varieties are quite good at preserving timber such as fencing in your garden (now that creosote is hard to come by). It has no place on a salad (but come to that, neither does lettuce).
//...but really like Romaine, in sandwiches egBLTs.//
One thing that should never be served up on the same plate is hot cooked meat and cold salad. Put the salad in a dish and serve it as a side (with the salad dressing served as a side to that so that it can be easily discarded untouched). I don't know the history of BLT sandwiches but whoever came up with the idea needs a sound thrashing.
My favourite leaves are rocket and basil (big-leaved, full-bosomed balloony rocket). They've got lovely flavour.
Soft, floppy lettuce I find boring, but little gem and cos and oak-leaf are fun, as are spinach and water-cress.
All these leaves add valuable vitamins and minerals to the diet.
Rocket and spinach for me...at least they've got flavour.
A big...very crispy...wedge of iceberg is great with a blue cheese dressing. But that's about the only acceptable way to eat it.
