I make mine this way
1 onion finely diced
2 cloves garlic crushed
500g minced beef
1 carton passata - I use the lidl one
italian herbs - about 1/2 tsp
1/2 tsp sweetner
seasoning
I spray pan with fry light and add mince, onion and garlic, brown off and drain any excess fat, add pasatta, herbs, sweetner and seasoning. Cook for 20-30 mins.
For the sauce
2 eggs
1 tub of vlf cottage cheese not sure of size I use aldi.
a pinch of italian herbs
seasoning
blend all of those in a jug, I sometimes syn a bit of cheese to put in, but you don't need much.
Place a wee drop sauce in the bottom of your dish, cover with lasange sheets, 1/3 white sauce, 1/2 the remaining meat sauce, lasange again, 1/3 white sauce, remaining meat sauce, top with white sauce and sprinkle with an A or B allowance of finely grated cheese.
I like to make mine in the morning and leave it sitting all day before I cook it. Gas 5 for around 40 minutes, or whatever you would normally cook one for.
It is delicious and really easy to make.
