We treat rocket like lettuce and use it similarly. Most often, we make salads from it and add it to sandwiches. Italians even use it on pizza. However, rocket belongs to the cruciferous vegetables.

Apart from traditional lettuces, such as 'Cos', 'Iceberg' and 'Butterhead', there are many others to try, including loose-leaf types and oak leaf lettuce, radicchio, rocket and endive.
