I wasn't going to make this bread. Casatiello is a brioche-like bread that is Italian in origin, and traditionally contains salami and cheese. I'm a life-long vegetarian, so the salami was definitely out, but for some reason I couldn't think of a substitute. Of course after I made the bread it dawned on me that sun-dried tomatoes would be fabulous, but since it didn't occur to me at the time - plus I didn't have any - I used toasted walnuts.
This was a delicious bread. The nuts and cheese complemented each other beautifully, and the bread itself was amazing. Light and rich at the same time, with a nice crunch from the nuts and wonderful little cheese pockets. I made a large loaf in a 9" pie pan - which made great sandwiches - and 6 rolls. I'm so glad I went ahead with this one, and I can't wait to make it again with sun-dried tomatoes.
