From the beginning I deviated from the recipe, using coconut oil instead of olive oil and butter for greasing. I used paprika instead of nutmeg, coconut cream instead of heavy whipping cream, used only a fraction of the cheese, and used less spinach because I didn't have quite that much. It was still delicious!
The second time I deviated even further, I used roasted dijon/paprika pork roast, which on its one was delicious (inspired by the tastes of deviled eggs), used frozen spinach, more onion, and used coconut cream again and less cheese. Also took more pictures:

A little bit of cheese.
See the lovely layering.
All baked and yummy, I just bake until the cheese is nicely baked since everything in it is already cooked.
Ah, steamy beautifulness!
I still have many more ideas for experimenting with this simple basic idea.
