Lettuce containers are important kitchen storage solutions. We have a no-throw out food policy in our home. That means if we buy the food, we eat it. So I carefully plan menus and snacks, so that the food is in the house to easily and quickly make a planned meal. Both my husband and I love crisp salads and the way that chopped lettuce goes with beef and olives in tacos and dishes like that. So every week I buy 3 or 4 heads of lettuce - and then the game is on to make sure they last the whole week.
There are lettuce containers that will store the entire head of lettuce. That's great for the greens at the end of the week. However, I usually have to use a salad spinner to wash and dry a few heads and then store them in other containers.
