Put the quenelle buns on a baking sheet and bake for 35 minutes.
Meanwhile, heat some water in a saucepan.
When the water comes to the boil, put the 4 hot dogs in the pan and follow the cooking instructions on the packet.
Put the heavy cream and Comté cheese in a saucepan and melt gently over a low heat for ten minutes.
When the quenelle buns come out of the oven, split them lengthwise like a hot dog bun.
Put a generous spoonful of Comté cream in the center, top with the hot dog then add a dash of mustard, a drizzle of ketchup and finish with some fried onions
