Today was my first day eating kale. I baked them at 350 spread on a cookie sheet until they were brown on the edges. First cut the leafy parts off of the stem (and compost the stem, of course) and tear them into bits. Coat them in a bowl with about a tablespoon of olive oil and another tablespoon of seasoning salt. When they're coated, lay them on the cookie sheet and bake.
The texture of the baked leaves is like a crispy, extremely thin potato chip. They taste similar to a chip also, but have a green flavor to them. I personally liked them and suggest trying it yourself! If they weren't so thin, I think they'd even be wonderful with a yogurt dip.
