Banana chocolate chip soufflés

Instructions

• Preheat the oven to 230°C/450°F/Gas mark 8. Lightly grease six
  175ml/6fl oz ramekins.
• In a bowl, beat the egg whites with an electric mixer until soft peaks
  form, then gradually beat in the sugar until the mixture holds stiff peaks.
• Thinly slice the bananas onto the mixture, and gently fold in the
  chocolate chips.
• Arrange the ramekins on a baking tray, and divide the mixture evenly
  among them. Run a knife around the sides of the ramekins, and bake the
  soufflés in the middle of the oven for 15 minutes or until golden brown.
  Serve immediately.
