Turn your Pit Boss grill to “smoke” mode, let the fire catch and then set to 350 degrees F (177 degrees C) to preheat.
Smear softened butter all over the bottom of a baking dish. Slice potatoes as uniformly as possible.
Place enough potatoes in the pan to cover the bottom. Add some of the bacon, ham and corn on top of the potatoes. Repeat this until you’ve created a few layers and have used all the potatoes, ham, corn and bacon.
Add 1 tbsp of butter and cover with milk, till it’s almost covering the mixture. Add salt and pepper to taste.
