This is a delicious side dish. The recipe is really easy, it just requires a lot of baking time.
1 pound of regular potatoes
1 pound of red potatoes
1 pound of sweet potatoes
1 pound of blue potatoes (you usually have to go to a farmers market or health food store. If you can't find them, you don't really need them, but you'll be missing out because they are really good.)
Slice potatoes very very thin and place on baking sheet. Mix all potato slices together and drizzle with olive oil. Top with fresh rosemary and garlic salt. Roll everything around together in pan and put in over. Bake on 400 for 45-75 minutes (depending on how thick the slices were and how crispy you want the potatoes.) Occasionally mix the potatoes around in the oven.
