Red onions are full of cancer fighting flavonoids but they rarely get the chance to shine on their own, until now. We’ve simply baked sweet red onions in sweet balsamic vinegar. They are so...


  • 2 medium red onions, peeled and quartered
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon olive oil
  • Salt and pepper, to taste

Chef Tips

For extra sweetness, use Saba, which is a concentrated form of Balsamic vinegar.
