Via Facebook, I found this great list of healthy substitutions for baking. Some things I've tried, but I really want to try the avocado sub. We've made avocado ice cream and loved it. Let me know if you try anything new and how it works out. Can you tell you used a substitution?
I've glanced through some of this Eco Chic Table part of the site and it seems to have some great foodie info.
I am looking forward to checking out the rest of the Organic Authority site.
