I have made this basic recipe more times than I can count. However, I do a few slightly different things. First, you do not need the mayo. It tastes just as yummy without the extra calories. In fact, I usually use the 1/3 fat cream cheese. I mix the dressing and cream cheese together and refrigerate a few hours (overnight is even better). This makes it harder to spread, but the taste is better. Then spread (not too thick) on party rye. I find the square "manufactured kind" holds up better than the fresh bakery type, although the latter tastes better. Slice the cucumber as thin as you possibly can and top with a sprinkle of dill. These are by far the easiest appetizer I make and one of the most well-liked. The way I make them, I use 1/2 loaf of bread and about a 1/2 cucumber, so double if you want to use it all.
