In a small saucepan stir together vinegar, stevia/sugar, and salt. Bring to a boil, then remove from heat.

Pour mixture over onions in jar until full. Place the lid on and let cool to room temperature.

Place the lid on to seal and refrigerate.

Layer two to three tablespoons of the dressing in the bottom of the jar.

Continue layering first five ingredients.

Fill rest of the jar with tightly packed romaine, or any lettuce of choice.
