1/4 cup hot water
1/3 cup sugar
1 (8-ounce) bottle Italian dressing
3 medium-sized cucumbers, cut into 1/8-inch slices
1 medium-sized onion, cut into 1/2-inch slices
In a medium bowl, combine hot water, sugar, and Italian dressing. Add cucumbers and onions.
Mix well then cover and chill at least 2 hours before serving.
The longer you let the cucumbers marinate, the more flavorful they become. If you like them really crispy, then you should plan to eat them within a day (which should be no problem since, once you start, it's hard to stop)!
