Tomatoes are very common vegetables when dumpster diving. One has to be more careful, though, when getting it from dumpsters. To play safe, don't take tomatoes with a broken skin since it is possible that some contaminants have gotten inside, which can cause a sickness. If the skin is intact, a simple cleaning with water will do, along with cutting off the overly soft parts of tomatoes. Very soft tomatoes can be used to make pasta sauce or tomato juice.
