Missing Kale from Ingredients

When there are confusing instructions in a procedure for something on the Internet, the first thing to do is to see if those instructions were posted elsewhere.

In this case it took me ten seconds to locate the recipe on the author's blog:

https://www.livingminnaly.com/allposts/2014/9/5/farro-veggie-stuffed-peppers?rq=farro

where the ingredient list includes the missing item.

Note that this type of sleuthing is not specific to Food52 nor food recipes. It applies to all types of instructions that are posted on the Internet.
