Weight Watcher's Cucumber Cooler

This is the same Cucumber Cooler recipe my family loves except I have taken out the sugar and replaced it with Stevia.  The best part is that it is 0 points per serving on Weight Watcher's.  This makes about 8 - 10 servings (about 12-14 cucumber slices per serving).

Weight Watcher's Cucumber Cooler

1/4 cup white vinegar
1 Tablespoon lemon juice
6 packets of Stevia (I use Pure Via)
1 teaspoon salt
1/8 teaspoon pepper
1/4 cup chopped onion
3 - 4 medium cucumbers thinly sliced
1/4 teaspoon celery seed

Mix together.  Chill in refrigerator for at least 1 hour before serving. I like to make this the night before.
