What makes these tuna medallions stand out is the addition of a pomegranate vinegar. Pomegranate vinegar is a ruby-red vinegar with a perfect balance of fruity sweetness and crisp acidity. It balances out the olive oil and seasonings while adding a subtle sweetness.
Pomegranates also are a nutritional powerhouse! Providing vitamins C and B5 and potassium, pomegranate juice has been shown to prevent bad cholesterol (LDL) from oxidizing, which helps keep heart disease at bay. (source: eHow Health)
