Watercress sandwiches are so much fun to make and eat. They are great for tea time or for a light summer lunch. All you need is a bunch of watercress, cream cheese and rye bread. I usually use mini cocktail loaves of rye bread, but this time I just used regular rye bread and cut the sandwiches into quarters. Some people like to cut off the crusts, but I think they are the best part of the sandwiches!
