If you ever wash them once, you will see that they DO need to be washed. I rinse mine a couple of hours before the meal, spin them dry and put them in a plastic bag with paper towels. They are wonderful by meal time. I also pick out the core of the romaine, radicchio, etc. I don't like those parts in my salad. I buy many different types, but like the mixes to add to whatever greens are on hand if I have to make a lot of salad. But, I almost never make the exact same salad twice. It is always a surprise to all of us. One thing I really like are the new flavored cheeses by Sargento (I think). They make even a plain salad taste special.
