Each bag contains 50g of dried sea lettuce Once rehydrated, it can be eaten as a solo vegetable One bag should serve between 15-17 servings Sea lettuce is a common type of seaweed that often can be found attached to rocks, but if it does become detached from the rocks, it will continue to grow and can sometimes create a big floating colony of sea lettuce. Our sea lettuce has been dried to make it easier to store for longer periods of time. When you want to use it, all you need to do is soak it in some water to rehydrate it and off you go! It\'s a great option for salads, or you can combine it with tomatoes, onions and peppers to make a divine ratatouille.
