Over high head in a large non-stick saute pan, heat olive oil and add thinly sliced onions to cook for 15 minutes or until golden. Reduce the heat to low and cover with a lid. Cook for an additional 35-45 minutes or until completely limp and caramelized, stirring every 5-10 minutes so they don't stick. There should be no crunch left in any of the onions and they will be nice and sweet.

Spread the cooked onions thin over a cutting board and let cool. Dice into small pieces.

Meanwhile, combine the cream cheese, sour cream, Parmesan, red wine vinegar and thyme. Add the cooled onions to the mix and season with salt and pepper. Stir well so everything is fully mixed and store refrigerated.

Serve chilled with crackers, crostinis or fresh vegetables for a great snack!
