Place the honey and sugar in a saucepan and heat on a medium heat until it comes to the boil. Boil for 3 minutes, then turn off the heat and stir in the salt and peanut butter.
Place the popcorn on a large tray and pour the peanut butter mixture over. Toss together until well mixed (it will be sticky), then spread out. Leave to cool for 5 minutes, then drizzle on the melted chocolate.
Leave until the chocolate sets, then break into pieces and toss together with the chopped snickers bars before serving.
