Cut sweet potato into half-inch thick round slices. Drizzle sweet potato with olive oil, salt and pepper, toss evenly to coat. Place sweet potato rounds on a baking sheet
Bake for about 20-25 minutes or until the sweet potatoes are tender and slightly crispy at the edges
Place a small piece of Brie on each round, allowing the residual heat to melt it slightly. Sprinkle dried cranberries and chopped walnuts over the Brie
Return the baking sheet to the oven for an additional 5-7 minutes, or until the Brie is melted, and the toppings are warmed through
Drizzle honey over the sweet potato rounds for a touch of sweetness
Garnish with fresh rosemary for a pop of color and added flavor. Serve sweet potato rounds warm as a delightful appetizer or side dish
