Add flour, salt, and baking powder to a mixing bowl and combine.
Make a small well in the middle of the bowl and break the egg into it.
Whisk the egg into the mixture gently until it thickens.
Start adding leftover soup gradually to the mixture and continue stirring to make a thick batter.
Don’t overmix.
Grab a medium size frying pan and lightly coat with cooking oil or butter.
Place the frying pan on the stove and set the heat to medium.
Once the frying pan is heated, pour the batter into a small circle.
Let the batter heat until small bubbles appear on the surface of the pancake. The bottom side will turn golden brown by this time.
Now turn the pancake using a spatula and cook it until the other side turns golden brown. Turn only once for tender pancakes.
Remove the pancake from the frying pan and serve with proteins, salads, and other savory dishes.
Repeat until the batter is used up.
