Until California cooking really hit its stride, mesclun, the French mix of baby greens was an unknown commodity in the US - now you can find it at every grocery store. Spring is a great time to try out new types of lettuce mixes from your farmer's market as the baby lettuces will just be poking their heads out of the ground. Make sure to use them quickly, although you can soak them for thirty minutes in cold water to restore crispness. You can even throw in fresh herbs and flowers to add extra color and flavor.
