This is a wonderful weeknight winter recipe! I found it from the below blog via Pinterest and I have not reviewed the other recipes on this blog but this one is great! It is very simple, weeknight/worknight friendly (crockpot) and a great vegetarian (vegan if you skip the feta) option. I took the blogger's advice and chopped the onion and celery the night before. Instead of feta, my husband added plain yogurt for creaminess which would be an option if you aren't avoiding dairy.
