Preheat oven to 425 degrees F (218 degrees C).
Peel and slice sweet potatoes into 1" thick rounds. Place them on a roasting pan. Drizzle with melted butter and sprinkle with salt. Toss to coat evenly and distribute so they aren't touching on another. Bake for 20 minutes. Using a pair of tongs flip each potato and bake for another 20 minutes.
In a small saucepan simmer the honey, orange juice, and cinnamon for 2-3 minutes or just to heat through. Serve with potatoes.
