Slice potatoes (2lg) into very thin slices (1/4 inch). Toss potatoes in (3Tbsp) olive oil, Italian seasoning (1tbsp) and salt (1tsp) in a ziplock bag to coat. Place in a single layer on a baking sheet lined with foil. Bake at 450 for 15 -20 minutes, until lightly brown. Top with Parmesan cheese and bake an additional 5 minutes.
Slice whole potatoes almost all the way through, so that the slices are all still attached at the bottom of the potato. Drizzle with olive oil and your favorite potato seasonings, bake for about 40 minutes at 425
