I saw something similar and decided to try this. They turned out alright, but it was a lot of work.
First, I used a cutter to create small cylinders of potato and then I ran them through the food processor to slice them thinly.
Then, I coated the slices with olive oil and a sprinkle of sea salt. Stacking them in a cupcake tin, I baked them at 350˚F until they were tender.
Allow the potatoes to cool slightly and pile a few into a stack; garnishing with tomatoes, basil and thyme.
