 after you wash them. Another thing I want to point out is some people a way to save time is to buy already washed salad greens that are in a bag. And please believe that when they say that they've been washed. The research has shown if you do go ahead and rewash lettuce that's bagged that says it's ready to eat, you'll actually do more contamination. So if they've done that work for you, enjoy the benefit of it.
