Sugar Free Mom's recipe for cucumber dill salad with no-sugar-added dressing uses stevia in the place of sugar. To make this recipe, remove the seeds from 2 English cucumbers, and then slice the cucumbers thin. Combine the sliced cucumbers with 1 cup of sliced red onion and 1 1/2 teaspoons salt in a bowl. Place the mixture into a colander and allow the liquid to drain for about 20 minutes.
Press the mixture to remove excess liquid before rinsing with cold water. In a separate bowl, combine 2 tablespoons white wine vinegar with 1/2 teaspoon powdered stevia extract or 1/4 teaspoon liquid stevia extract. Add the cucumber and onion mixture to the dressing, and top it with 2 tablespoons chopped dill and juice from 1/2 a lemon. Mix well, and store the salad in the refrigerator until ready to serve.
Spoonful of Sugar Free's recipe for cleansing cucumber salad omits sweetener altogether, and it instead relies on the mild natural sweetness of cucumber and cherry tomatoes. To make the dressing for this salad, combine 1/4 cup each of white vinegar and apple cider vinegar with 2 tablespoons balsamic vinegar and salt and pepper to taste.
