Wash and dry the kale. Tear or cut the leaves into pieces, cutting out the tough center stem.

Toss the leaves with the olive oil, and then sprinkle on a few pinches of sea salt.

Lay the leaves on a cookie sheet (see pic below) and bake at 350°F for about 10 minutes.

Careful, though: If you bake them too briefly they won't get crispy, but go too long and they'll be burned. Check them at 9 minutes, and if they're not crispy yet, give them a couple more minutes and check again. You may need to pull some out sooner than others.
