In the frying pan, fry off your onions and mushrooms until soft.

Add the mince, purees, sauces, stocks, herbs and spices to the pan and stir to combine.

Add in the tomatoes and simmer on a medium heat until cooked through.

In a saucepan, melt the butter.

Add in the flour and stir until a paste is formed

Add in the milk in small amounts, stirring each time to combine the milk in with the paste.

Once all the milk is in the pan, add in the cheese, mustard, salt and pepper and stir until thickened.

In your lasagne dish, add in half of the bolognaise and spread over the bottom of the dish.

Add the pasta on top until the bolognaise is covered.

Add 1/3rd of the sauce on top of the pasta and then repeat the steps once.

Pour the remaining white sauce on top of the lasagne, sprinkle with cheese and bake in the oven at 180°C for 30 minutes until golden brown and bubbling.

To make it easier to slice, leave the lasagne to rest for 5 minutes before slicing.
