The simple answer is yes, you can make them – but I think the question being asked is are they Free on Extra Easy!
Lasagne crisps are not free
Lasagne sheets are designed to be used to make lasagne. Using them to make crisps or Doritos would mean that they’re being used in the way they’re not designed – and worryingly, it would be possible to consume the whole box of lasagne sheets – certainly not healthy for you in one go!
You should syn these are the standard crisps value, or instead, just use a packet of normal Dortios and count the syns.
