In a large bowl, combine the potatoes, flour, and pepper.
Add the egg substitute or egg white and mix until combined.
Coat a large nonstick skillet with cooking spray and heat the oil over medium heat.
Drop the potato mixture in the oil in 1/4 cup measurements, keeping each pancake from touching.
Cook about 3 minutes each side or until browned. Remove the pancakes from the skillet and drain on paper towels. Repeat with the remaining mixture.
Top with applesauce and sour cream.
