Preheat oven to 375 degrees F. Lightly grease a baking sheet with cooking spray and set aside.
Mix flour, salt, pepper and paprika in a shallow plate. In a small bowl, lightly whisk the egg and stir in 1/2 cup of hot sauce. Spread panko in a separate plate. Dip each cutlet in flour, then egg mixture, then panko, allowing excess to drip off in between each plate.
Place cutlets in the oven for 7-10 minutes or until cooked through.
In the meantime, melt remaining hot sauce and butter in a small saucepan until melted. Turn off burner and set aside.
Spread a little Ranch dressing on one side of your bread. Top with lettuce and a chicken cutlet. Top with the hot sauce mixture and another piece of bread. Enjoy!
