A quick and refreshing cucumber onion salad with a tangy vinegar dressing, perfect for hot summer days and easy to customize.
Use a mandoline slicer for thin, even slices. Chill the salad at least 30 minutes for best flavor and texture. Drain excess liquid before serving if cucumbers become watery. Soak onions in cold water for 10 minutes before mixing to mellow sharpness if desired. Variations include adding vegan sour cream for creaminess or red chili flakes for heat.
