Cucumber Herb Vinaigrette

We fell in love with this recipe last summer and we're still using it this summer. It's easy and very good.

Thank you very much. This looks wonderfully delicious. However, I don't really see the need for sugar. I imagine, though, if one wants a sweetener, honey would be an excellent and healthier substitute for sugar...or even, perhaps, balsamic vinegar instead of sugar and red wine vinegar...that is, if you want a little sweet. Personally, I'd prefer no sweetener using it on a salad, but maybe some sweetener if I use it like a marinade or sauce for salmon.
