Should be able to get wholemeal lasagna sheets in most high street supermarkets, failing that try your local health shop as Alison suggests.
I have tried Sainsburys, Asda and Tesco Toby but can't find lasagne sheets - just pasta. Looks like a trip to town to get it. Thanks for responses.🙂
I find my asda store places the sheets right at the end of an aisle, right hand side. If that helps,
