Once a week I make a huge batch of basic salad which includes 2-3 different kinds of lettuce, radishes , onions, red cabbage & sliced carrots. After everything has been washed and chopped, I use a salad spinner. The salad then goes in a zip-lock bag with paper towels which help absorb extra
moisture. The air is squeezed out.. When I'm ready for a salad I add what ever soft ingredients I need to fit my plan...avocado, cucumber, red & yellow peppers, cheese etc. The basic ingredients will stay fresh and crisp for at least a week. The best part though is having salad always ready.
