I baked a lasagne but substituted the noodles for thinly sliced zucchini.
Sauce: Heat oil in a pan 1 minute, add minced garlic and red chili flakes 2 minutes, add chopped red onion 5 minutes, (OPTIONAL!) add minced beef until cooked, add roasted red bell pepper (chopped) and a can of chopped tomato and chopped fresh basil and simmer until heated and sauce thickens. Set aside. S&P to taste throughout.
Slice zucchini with mandolin if you have one and set aside. Very roughly chop fresh basil and set aside. Mix up of fresh buffalo mozzerella, grated pecorino, and shredded cheddar and set aside. Beat 1 egg and set aside.
Layer in a metal baking dish (better than glass - will give you crusty stuff around the edges!): sauce, zucchini, cheese, sauce zucchini, cheese, etc until you run out. Layer top w/ roughly chopped basil.
Bake at 200C for 30 minutes. Remove and brush top w/ beaten egg and a fine layer of grated pecorino. Return to oven for 15 minutes. Let stand 10 minutes before cutting and serving... this will let it 'solidify' and not run all over the plate, and also, the flavours are better once the return to a sensible temp.
Mmmmmmmm....
