Cut the bread into long rectangles by cutting horizontally.
Hold each slice over boiling water for a few seconds to soften. Press lightly with a rolling pin on a worksurface. Apply butter, then chutney on each slice. Sprinkle the vegetable mixture all over sprinkle cheese over it.
Carefully roll from on end towards the other as tightly as possible, without breaking the bread. Secure with toothpicks if required to hold. Chill rolls for an hour in the fridge, wrapped in a moist cloth. Remove toothpicks, cut into 1/2 circles and serve with spicy tomato sauce and french fries.
