Cook the potatoes with the skin (keeping the skin helps to keep the nice blue color) for 30 minutes in boiling water. Heat the cream in the microwave with the cheese, butter, bacon, salt, and pepper for a few minutes or until the cheese is well melted. Using a whisk, remove the crust from the cheese. Peel the potatoes, mash them, and pour the hot cheesy cream over them. Mix well. Place 1 teaspoon of salsa on each blue corn tortilla chip from Tostitos and, using a pastry bag or a spoon, place the potato mixture on each Tostitos chip.
