Cook sliced hotdog in the butter on medium-high heat in a non stick skillet. While the hotdog is cooking, beat together eggs, salt and pepper, mustard powder, and cream, until it's smooth. Season with salt and pepper. Remove hotdog when cooked the way you like and drain on paper towels. (I like mine to bubble and the outside gets a bit crispy.)
Reduce heat to medium and add the egg mixture to pan, distributed evenly. When underside is cooked, add the hot dog, cheese, and ½ of the onions. and fold over. Cook another minute or two until the cheese begins to melt.
Fold one edge up then slide out of the pan so it inverts onto a platter tri-folded into a burrito shape. Top with the remainder of onions, pickle relish, and ketchup.
