The Basic Green Salad makes an excellent base for prep-ahead salads. It will stay fresh for 2-3 days in your fridge crisper and could be mixed and matched for different tastes and textures with all sorts of fresh vegetables, sprouts, toppings and dressings. Honestly, the BGS is a staple in our household - it's loaded with nutrients, enzymes, vitamins and minerals you just won't get from your typical store-bought iceberg lettuce mix.
