I'm afraid you're going about it all wrong, dear heart. You see, this actually sounds nice. My recipe is far more realistic:
1. Put frozen onion and garlic into a cold pan with worryingly cheap mince of whatever fat percentage you like and a tin of tomatoes or clamato juice - in fact, anything vaguely tomato-adjacent. Don't forget plenty of black pepper. Bring to a rapid boil and let it go for 3 hours while you witter about absolute nonsense on Twitter. Be sure to mention at least one ailment or blow a mild inconvenience up into a floridly described tragedy so you can reap the pity while the lasagne is in the oven.
2. Blend lard, plain flour and corn milk to make a white sauce of questionable origin.
3. Layer the meat slop in whatever dish you have to hand with pasta sheets and the cold, watery, starchy, briny, unctuous corn milk.
4. Bake at hot temperature until the white sauce thickens. It may be incinerated at this point. It probably doesn't matter. Post a tweet to let everybody know that SB hoofed down multiple servings and declared it the most bestest lasagne EVER. Don't even pretend to do the washing up, we've seen the state of your kitchen.
