Choose either a store-bought or homemade tortilla and lay it on a flat surface. Add mayonnaise and ketchup to the center of the tortilla, and use the back of a spoon to mix the condiments together. Spread the special sauce across the tortilla. Then, lay slices of cheese over the sauce.
In a small mixing bowl, whisk together the egg, heavy cream, salt and pepper. Melt butter in a non-stick skillet over medium heat, then pour the whisked egg mixture into the pan. Stir the eggs as they cook in the butter until they scramble. Set the scrambled eggs aside to cool for just a minute or two.
In a clean skillet, cook slices of bacon until they’re crispy. Arrange the scrambled eggs in a strip along one side of your tortilla. Then, lay the strips of bacon next to the eggs. Gently roll the tortilla over the eggs and bacon, then continue rolling up the tortilla as tightly as you can without tearing it.
Slice any messy ends of the tortilla off. Then, cut the rolled tortilla into 4-6 pieces. Serve warm or eat as a chilled snack. You can also refrigerate and eat leftovers.
