Seared Tuna with Sweet and Sour Cipollini Onions Recipe


  • 3 tablespoons olive oil
  • 1/2 pound ciopollini onions
  • 1/4 cup balsamic vinegar
  • 1 tablespoon of sugar
  • 1/4 cup of water

  1. In a large saute pan, heat 2 tablespoons of the olive oil over medium heat.
  2. Add the ciopollini onions and cook, until lightly browned on all sides and slightly softened 8-10 minutes.
  3. In a small bowl, mix together the balsamic vinegar, sugar, water and a pinch of salt, and add to the onions.
