In a mixing bowl, add the flour, potato starch, salt, and water. Mix to combine.
Add the sliced vegetables. Stir to mix all together.
Place a frying pan over medium heat. Add the oil and gently wiggle the pan to let the oil distribute evenly.
Once the pan is well-heating, pour the mixture onto the pan and spread it out a big to make it into a single layer.
Cook on the first side for about 5 minutes over medium heat. Then flip to cook the other side for another 3 minutes or until both sides get slightly brown.
Preparing the sauce while cook on the first side: Add all sauce ingredients in a small bowl and mix well.
Once the pancake is down on both sides, transfer it to a cutting board and chop into the shapes you like. I chop them into triangle slices like pizza! Serve with the sauce. Enjoy!
