Cook the french fries and chicken bites according to the package instructions.
Coarsely chop the chicken bites.
Spread the french fries on an oven-safe platter. Sprinkle with about half of the cheese. Top with the chopped chicken bites. Then sprinkle with the remaining cheese. Return to the oven at 350°F for about 5 minutes or until the cheese melts.
Drizzle with the ranch dressing and serve.
