A salad spinner is a great tool for rinsing and drying your lettuce. Simply remove the inner strainer from the chopper. Chop your lettuce and put into the inner strainer. Rinse the lettuce under cold water and drain. Then add the strainer back to the spinner, put the lid on and pull the chord to force excess water off the lettuce.
You don’t have to spend a bunch of money on a salad spinner. Mine cost around $10-15.
