Recipe for the carnival - Lasagne

Now, being Summer here at the moment, I don't cook this too much at the moment, but thought, what the hey, all of you who are in Winter at the moment would appreciate this. It is very yummy, and very filling. Not one for those who are trying to lose weight...

Lasagne

500g (17.7 ounces) beef mince
1 onion
Olive Oil (not a lot, just enough to brown the mince in)
810g (28.6 ounces) can crushed tomato
2 packs tomato paste, each are 140g, 4.9 ounces (we have a brand here called Leggo's that sells these in 2 or 4 packs, not sure how widespread they are)
salt and pepper to taste
2 Tbsp chopped parsley
garlic to taste (I think there is no such thing as too much garlic, so adjust to your own taste)
1/2 tsp Italian herbs (if you don't have a mix of this, just oregano is nice)
sherry (enough to fill one of the Leggo tubs, so see amount above)
Lasagne sheets (fresh, not dried, I haven't been able to cook this successfully with dried)
Tasty cheese slices
500g (17.7 ounces) grated mozzarella, tasty cheese, parmesan mix (or whatever of these cheeses you feel like)
Jar of bechamel sauce, optional (yes, it can feel like cheating to not make your own up, feel free to do this if you like, I just can't be bothered.)

Brown meat and onion in olive oil until the liquid is gone.
Sprinkle parsley, Italian herbs, garlic, pepper, salt on top of the can of tomatoes.
Pour this mix of tomatoes and herbs into the meat.
Mix this in, then add and mix the tomato paste.
Turn heat down, and add the sherry.
Simmer for 1 hour, uncovered on a low temperature.
In a large baking dish, make a layer of the lasagne sheets, then a layer of the cooked meat. Add some bechamel sauce if you are using this, then add a layer of cheese slices.
Add another layer of lasgne sheets, and then another layer of meat.
Put some more bechamel sauce on if using, then sprinkle the grated cheese on top.

Bake at 150 degrees Celsius 300 Farenheit for 40 minutes.

Serve with a green salad and a healthy appetite!
