Preheat your waffle iron according to the manufacturer’s instructions.
In a large bowl, combine the pancake mix, milk, oil (or melted butter) and egg. Stir until blended.
Lightly grease the waffle iron with a small amount of oil or non-stick cooking spray.
Pour the batter onto the preheated waffle iron, being careful not to overfill it, since the batter spreads when you close the iron.
Close the waffle iron and cook for 3 to 5 minutes. The time varies depending on your waffle iron.
Carefully open the waffle iron and check that the waffle is golden and crisp. If it is not, close the iron and cook a little longer.
Repeat with the remaining batter.
Serve the waffles immediately, topped with sliced strawberries, whipped cream and mint, with syrup on the side.
