The potato pie - red bliss potatoes sliced on a mandolin, red onion, and finely chopped rosemary all tossed in olive oil. I rinsed the potatoes in several changes of water to get rid of some of the starch, then sprinkled about 1/2 tsp of salt and let it sit for awhile to pull out some of the water.
