Preheat oven to 350 degrees, spray a muffin tin with non-stick cooking spray. Set aside.

In a large mixing, whisk together the eggs, salt, pepper, and kale. Gently mix in ½ cup of the Havarti cheese. Fill in the muffin tins with the mixture until ¾ of the way. Add the other ½ cup of shredded cheese on top of the mixture.

Bake for at least 25 minutes.
