I always thought making lasagna, is like a religious experience for me.
And it is I mean, it's always different depending, on what I have, for meat or no meat, and vegetables, and cheeses,
You can use cream cheese, gruyere and cheddar believe it or not, definitely need mozzarella though, haha,
All those epic lasagnas I've made, geez, amazing what I've learned, NO failures, ever, and so many lessons in leftovers, appreciating the depth of flavors the gifts of the day, and those yummy memories, emmmm, boy.
When you can pause, a -second- to appreciate the finer things in life, like this here leftover lasagna.
It might be what makes you a good chef, I don't know,
