Preheat oven to 375.
Spread kale on a large stainless steel baking sheet.
Spread the ghee in chunks over the kale, so that it's divided up and spread out.
Sprinkle the salt and oregano over the whole tray of kale.
Put in the oven and set a timer for 5 minutes.
When the timer goes off, remove the kale and stir very well, ensuring that the melted ghee coats every bit of kale, and the seasonings are well dispersed.
Place back in the oven and set the timer for another 10 minutes.
Again, remove and stir the kale, then place back in the oven for another 5-10 minutes, checking halfway through to be sure the kale isn't getting too charred.
Once the kale is crispy and slightly charred on the edges, remove from the oven and allow to cool before eating (or risk a burned tongue- not that I burn my tongue every time because I can't resist popping a piece of kale right in my mouth!).
