Preheat oven to 400 degrees. Lightly grease a muffin pan and set aside.
In a small bowl, combine olive oil, nutrtional yeast, ½ tsp, pepper and chives.
Using a mandolin or very sharp knife, careful slice potatoes very thinly, about 1/16 - ⅛ of inch.
Transfer potato slices to a large bowl and sprinkle with a pinch of salt. Toss to coat.
Pour the oil mixture over potatoes and toss to thoroughly coat. Hands work best for this.
Layer potato slices into each of the wells of the prepared muffin pan, filling each to the top.
Sprinkle with additional nutritional yeast and chives, if desired.
Bake for 25-30 minutes, until potatoes are browned around the edges and tender through.
Allow to cool for a few minutes before using a fork to gently lift the stacks from the pan. Serve warm.
