Fried wonton is the snack that vanishes off the table bro. They are small, crispy and moreish, so a plate of 6 is gone before you have clocked it. But each one is a thin wrapper deep-fried until crunchy, and that crunch is oil. A plate lands around 360 calories, and the dipping sauce, especially if it is mayo, only adds to it.
The actual filling, a little pork and prawn, is tiny. You are mostly eating fried dough. If you want the same flavour lighter, steamed wonton in soup is a fraction of the calories because there is no fryer involved. Fried ones are fine as a shared starter, just do not treat a whole plate as nothing.
