Chop the garlic, 5 seconds, speed 5. Next chop the celery and onion, 10 seconds, speed 4.
Heat the oil in a large pan and add the garlic, celery and onion. Saute over a moderated heat with the lid on for 10 mins, stirring occasionally. You want to sweat the veggies, not brown them.
Add the pork and beef mince and continue to cook, stirring until almost cooked through and most of the liquid has gone.
Add the herbs.
Turn the heat to high and add the red wine so it sizzles and reduces.
Chop the mushrooms, 3 seconds, speed 4. Chop the carrot and zucchini, 5 seconds speed 4.
Then add the rest of the ingredients to the pan, stir and reduce to a simmer for 1 hour with the lid ajar. When meat has approximately 10 minutes to go, preheat your oven to 180°C/350°F (fan-forced).
Rinse the Thermomix, dry with a paper towel, and make the bechemel.
Grate the cheese, 10 seconds, speed 6 and set aside.
Add the butter, flour, broth and milk into the bowl and cook, 10 minutes, 90, speed 4, MC on.
Once the bechamel has thickened, season with a pinch of salt and a grind of black pepper and mix in a quarter of the cheese. Thermomix, 10 seconds, speed 5.
To assemble, alternate layers of the meat and lasagne sheets finishing with a layer of the bechamel and the remaining cheese.
Bake for 30 - 45 minutes or until the lasagne is cooked through.
