If you use watery ingredients like cucumber or tomato, it's best to leave those separate until you want to eat the salad, or else they make it watery sometimes and don't do very well with the chopping process. Not a dealbreaker, but just a helpful tip. The 10 minute prep time is if you already have all of your ingredients prepped. It takes considerably longer if you have to do all the prep work. Usually takes me about an hour for a week's worth of salad.
