Really easy and I used what I had on hand, so it's super customizable!
Edit: I make this ALL the time now! It's become a staple in our house! I change it up a bit with whatever nuts and dried fruits we have. I also usually add cacao nibs to it. I change up the sweetener with either honey, agave, date syrup or maple syrup. The one thing I always keep the same is the sourdough!
