Fry the onion, carrots and celery in a little oil for 2-3 mins, then add the mushrooms and cook for another 5-6 mins, when they release their water, add mince and brown
Add tin of chopped tomatoes, stir and simmer on low for at least an hour
If making the bechamel, do it now. See my cannelloni recipe. (I didn't have time to make it.) After 30 mins, turn on the oven to 180. Get your lasagne tray and sheets ready
Start to layer up the lasagne. Meat, sauce and Parmesan. Continue until all ingredients finished. The final layer, add a little bechamel and Parmesan
Half way through cooking, some of the sauce will have leaked out. Using a spoon, scoop it up and add it on top. You want the top crispy but not crunchy
Leave to stand for 10 mins before serving. Enjoy :)
