I actually really love kale-  have you ever had it?
I love it! It's so good for you.  I like both the green and purple varieties. 
I've never seen purple kale - is it the same?
Yes, both the green and purple kinds have similar leaves. 
Is the purple as nutritious as the green?
I am not entirely sure about that. I just like the look and taste. It's like cabbage, which also comes in green and purple. Kale is actually a cultivar of cabbage. 
It's a type of cabbage?  I didn't know!  I love kale steamed with some butter and salt.  SO good!
Have you ever tried making kale chips? You basically dehydrate kale leaves in the oven with a little salt and oil.  They get crunchy like potato chips.  Really good.
