Easy Cucumber Salad

When I was growing up, my mom used to always make a quick, easy cucumber salad that we loved.  She just sliced the cucumbers into a bowl.  Then she sliced an onion (sometimes I use red onion to give is more color) and added fresh chopped tomatoes.  Finally she poured Italian salad dressing on top, tossed and served.  I make this quite often, especially when I don't have enough time to make my Cucumber Cooler.  My family loves cucumbers no matter how they are served.
