Add the beans to the tray of a lipped pan, in an even layer. Drizzle the melted butter evenly out over the top, and using a pair of tongs gently toss the beans with the butter until well coated.
Season the beans evenly, and liberally, with salt & pepper.
Preheat the smoker to 275 degrees. Add the beans, and smoke 3-4 hours, tossing them every 30 minutes- or until tender shriveled, and slightly browned in places.
Notes
After the beans are cooked, while still hot, but before serving- sprinkle the beans with shredded parmesan cheese. Lightly, but let it melt and enjoy!
