Cook waffle fries until crispy, according the instructions on the packaging.
When the fries have been cooked, while leaving them on the baking sheet, top each waffle fry with a couple small slices of corned beef and Swiss cheese.
Place baking sheet back in the oven under the broiler set to High. Broil until cheese is melted, approximately 1 to 2 minutes.
Remove baking sheet from oven.
Top each waffle fry stack with slices of avocado, sauerkraut, and a drizzle of Thousand Island dressing.
Garnish with a sprinkle of fresh parsley as desired.
Serve immediately.
