Preheat oven to 400 degrees F.
Place a sheet of tin foil on a baking sheet. Place individual waffle fries on the sheet and space evenly. Using oven mitts, place the baking sheet in the oven and bake fries for 18 to 20 minutes.
While the fries are baking, open the can of black beans using a can opener and spoon into a microwave-safe bowl. Cover the bowl loosely with plastic wrap and microwave on high for 4 to 6 minutes.
Using oven mitts, remove the fries from the oven and let cool about 5 minutes.
To assemble, evenly space the fries on a microwave safe plate. Top each fry with 1 tablespoon of the heated beans and then sprinkle with the cheese and olives.
Put the plate in the microwave and heat on high for 1 minute, or until cheese is melted. With oven mitts, remove the plate from the microwave. Top each fry with 1 teaspoon salsa and 1 teaspoon sour cream.
