The receipe DF use is as follows:

1 Jar bechamel sauce (dolmios)
1 jar chunky onion & garlic pasta sauce (dolmios)
500g - 1kg mince
grated cheese/pkt of pre grated pizza cheese
Lasagne sheets

Put lasagne sheets in boiling water for a few mins to soften, in large sauce pan brown mince, add pasta sauce & simmer till piping hot.
In large baking dish layer meat, white sauce,cheese, pasta - 2-3 times
Finish with white sauce & cheese cover with foil bake 45 min @ 180 degrees
Remove foil & bake further 10 -15 min or until cheese is golden brown


DF is lazy though, I prefer to make it from scratch
