Preheat oven to 350°F (180°C). Slice loaf in half lengthwise. Thinly slice cheese and evenly cover cut halves. Thinly slice berries and scatter evenly over cheese. Sprinkle each half with 2 Tbsp (25 ml) Demerara sugar. Place on a cookie sheet and bake in the center of oven for 10 to 12 minutes or until cheese is melted and begins to bubble. Remove from the oven and sprinkle with chopped mint. Makes 6 to 8 servings.
