Kale chips do NOT taste like potato chips. They taste like ass. Not literally, because like crocodile... I just have no clue. I said this Saturday night (the tasting bad part not the crocodile part) and the response I got from my vegetable hating friends was: "You need to put a LOT of salt on them. They taste like salt. They are delicious." I wish he had told me this before I made them. I do like vegetables but other than that we tend to have the same taste in food. If he tells me something is good it usually is and conversely; if he tells me I will not like something, he is right. If I was told to put a lot of salt on them so that they would taste like salt, I would not have made them.
Kale, when baked, has a bitter after taste that is not good. I think I would rather just eat spinach that is lightly salted.
