Whenever I crave for lasagna but only got some bread in hand I use the bread instead of pasta. Have you done that? Try, it's pretty good. So the layers would be buttered bread - bolognese sauce - cheese sauce and repeat them as many as you like. I had some leftover cream soup so I made cheese sauce out of it - just add shredded cheese, a little thickener if needed, and warm them up until become sauce. Oh I also added some spinach between the bolognese and cheese sauce layers.
What a lovely saturday morning breakfast.
