Notes
Use plant milk, a vegan spread and a vegan cheese for vegans, or just leave out the cheese part.
If you can't find lasagna sheets without egg, and you want to make this vegan, you could try making pasta, it's really not very difficult.
I've found that this can be used as a basic recipe for lasagna, just changing the ragu layer for all sorts of other things. I've done a lentil one, now this mushroom one, and a beetroot one may be next, although there are so many flavours to try, I can't decide which one to do!
