Cut the peeled onions lengthways into eighths and fry them lightly in the oil. Add the freshly squeezed clove of garlic (alternatively also granules) and deglaze with a dash of wine and the balsamic vinegar. Add pepper, salt and honey (alternatively sugar) as desired and season to taste.
Let it steep overnight and a delicious onion salad is ready, which tastes best with grilled meat.
