Lettuce is one of the most widely used and recognized vegetables in the world, and it is the most popular cold vegetable sold in the United States. There are four types of lettuce: romaine, butterhead, leaf lettuce, and iceberg. 

To Store:

Wash the lettuce in cold water. Store in a damp towel in the fridge either alone or in an air-tight container. Iceberg will keep for up to two weeks, romaine for 10 days, and butterhead and leaf lettuce for 4-5 days. 

Preparation:

Lettuce is best prepared raw, washed and spun in a salad spinner or patted dry with a towel. If the leaf is dry, the dressing will stick better! Lettuce makes a great addition to sandwiches, used instead of bread and, of course, as the base to any type of salad you can dream up!
