Prepare fries according to package instructions. Wrap 4-5 fries together with a slice of bacon and place packets/rolls on a baking tray lined with baking paper. Put in the preheated oven for 3-4 minutes to make bacon crispy.
Place 6-8 packages/rolls on a plate. Season with salt and pepper to taste. Serve with ketchup.
If you like crispy bacon, prepare the fries for less than the instructions on the package and bake it wrapped by bacon in the oven longer to become crispy.
