Preheat the oven (180°C/350°F/gas mark 4)
Place the mince in a large pan over medium heat, add a large glass of wine, the finely chopped onions, pepper and tomatoes and stir. Cook it for about ten minutes, stirring occasionally.
When it is nearly ready, add the chopped garlic. I always cut garlic with a ceramic knife because stainless steel can oxidise it.
Add the spices and stir for 3-5 minutes, then turn the heat off.
For the veggies, you have three options: fry them in oil (they will absorb it like a sponge!), bake them in the oven for 15-20 minutes, or use them raw.
Regardless of your chosen method, cut the potatoes, aubergines and courgettes in no thicker than one cm slices. Soak the potatoes in cold water for a few minutes (to get rid of the excess starch)
In a large baking tray, start with a layer of potatoes (sprinkle a little salt and dried oregano). Continue with a layer of aubergines and courgette (slightly salted).
The next layer is the prepared meat (add half of the béchamel sauce and mix well if you decided to go for it).
Continue with another layer of courgette, aubergines and potatoes, slightly salted.
Sprinkle a little dried oregano over this last layer of potatoes.
To avoid burning the potatoes, I usually spread a couple of tomato sauce spoonfuls over the last layer before baking it. If you made your béchamel sauce, lay the remains of it evenly over the entire surface.
Bake for 50-55 minutes.
Just before the time is up, grate some hard cheese on top and bake the moussaka for another 2-3 minutes or until the cheese starts bubbling.
