Back to the beef mix. Add the lemon juice next add the tomato purèe and 1/4 cup water. ( It has to be liquidy to soak the lasagne sheets.also the veg stock. Stir in and let simmerfor 5 minutes.

Put 2 ladels of the liquid in the dish first so it soaks the underneath of the sheets too.then add the sheet and break up bits to coverall sides. Then add two ladles of the beef mix full of the meat and veg.

If you find you have not enough liquid just add 1 tsp tomato purèe to 1/2 Cup of water mix and add to whats left of the meat.

The secound layer add what is left on top of the lasagne sheet, then add the sauce.then add the lasagna sheets. Next make some Cheese sauce and add on top of the lasagne sheet.
