Please allow me to introduce Scalloped Hasselback Potatoes!!
http://recipesineed.com/scalloped-hasselback-potatoes/ this is where you can find the recipe.
Bake for 45 mins then pour the half & half over and sprinkle with cheddar cheese and bake for 12 mins. Then enjoy!! But let cool first because I couldn't wait and it was really hot. :)
