8-ouncesplain Greek yogurt(or another 8 ounces of sour cream)
8ouncesof cream cheese, softened
Melt butter together with the olive oil in heavy skillet over medium-high heat.
Add onions and garlic.
Sprinkle lightly with the salt and sauté until onions begin to turn golden and caramelize. Stir frequently. This will take about 15 minutes.

Remove from heat and cool onions to room temperature.
