I thought everyone did the Miracle Whip dressing! LOL It is the first thing I learned to make when I was a kid.
1c miracle whip
tsp vinegar
1/2c sugar
mix thoroughly
Add more sugar or vinegar as needed to taste
This is similar to a cole slaw dressing so you can add a little condensed milk or I just add a bit of water to get a smother consistancy but I learned it with out either one added. It is just a matter of taste.
Just slice several cukes and add the dressing. Double it if you have a bunch of cukes. You can add onions or any other veggies if you want but I don't usually.
