In a large bowl mix the eggs, the sugar and the salt.
Add flour and milk. Mix well.
Add oil and mix.
Cook the pancakes
Heat a non-stick crepe/pancake pan over medium high heat. When it is hot, pour or scoop the batter onto the pan. Using approximately a little laden (1/2 cup) for each pancake. Tilt the pan with a circular motion so that the batter coats the surface. This should be a very thin coat.
Cook 1 to 2 minutes until pancake begin to lift from pan. Loosen with a spatula. Turn and cook the other side 1 minute.
The pancake is done when both sides are a light brown.
Repeat with remaining batter. Scoop it onto the hot pan and cook both sides of pancake.
Fill the pancakes
Spread each pancake with filling and roll up.
Notes
My kids eat the pancakes with cacao powder-sugar mix, Nutella or apricot jam but my favorite is the pancake with sweet quark (cottage cheese) filling.
