Mashed Potato Stuffed Mushrooms

1. 1

   Heat 1 tablespoon olive oil and butter over medium low heat in a large nonstick pan and cook onions for 45 to 55 minutes, or until caramelized, stirring occasionally.

   Meanwhile, bring a large pot of water to a boil over high heat. Add potato chunks to the pot and boil for 10 to 15 minutes or until fork tender. Drain and mash in a large bowl (yield should be about 1 1/2 cups). Mix mashed potatoes with buttermilk and salt until smooth; mix in crumbled feta.
