Start by preheating the oven to 180C. Line a loaf tin with non-stick paper.
Cut the eggplants into very thin slices. On a plate, mix the breadcrumbs with the garlic, onion, paprika and salt. Dip the eggplant slices in and spread them on the bottom of the form.
Follow with some mozzarella. Add a layer of mushrooms and then grated cheese. Another layer of eggplants and on top slices of cheese cut into strips. Add mushrooms and grated cheese on top.
Finish with eggplants, top with some grated cheese and add the remaining breadcrumbs. Sprinkle some red pepper on top and bake in a preheated oven at 180C for 25-30 minutes.
Remove from the oven and let your lasagne stand for 10 minutes before slicing.
