Maybe not strictly authentic, this lasagne is made with a homemade meat sauce, and homemade white sauce. (Although sometimes I cheat and use a shop-bought white lasagne sauce.) Takes a bit of time to prepare but I think it's worth it. I hope you do too!
If you use wholemeal lasagne sheets, you may find they stay a little 'al dente' after cooking - gives it a bit of texture!
I use Kaloo organic beef stock cubes. For the cheese, use whichever you like, such as Cheddar, Red Leicester, Double Gloucester, mozzarella, etc.
