My Mother In Law taught me how to make Lasagna years ago and the recipe has evolved into what it is today. It does vary depending on what I have on hand. Sometimes I use more cheese and if you can make it ahead of time and let it sit in the fridge all day or over night it tastes even better! It seems like a lot of steps but it's really not that bad, you could cook the onions and the garlic with the meat and sometimes I add a diced red bell pepper.
I never make this the same twice. This makes it interesting, my mother in law got me started cooking it and then it has sort of evolved. You really can't go wrong with it, the layers aren't set in stone so mix it up as you wish.
I've never made this using a recipe so I hope that this sounds okay. When in doubt follow the directions on the noddle package.
