I discovered wide flat lasagna noodles that you do not have to boil before you assemble the dish and bake it.   You put the noodles directly into  the pan as directed in the recipe on the back of the box and it really works.  I changed the recipe as follows.  I don't use more than one or two layers of noodles.  For meat I shred up a soy burger.  I add mushrooms.  I use liquid egg and fat free ricotta cheese and fat free mozzarella cheese.  Fat free ricotta is hard to find so I substitute fat free cottage cheese instead.  I've also use fat free cream cheese in a pinch and that works ok too.  I blend the substitute cheeses  to get rid of the lumps but that is not really too necessary.  I hope this helps.
