I made this easier by using premade toasts from the cheese section of my grocery store. They were a little pricey, but well worth it! It was awesome and even enjoyed by my 10 year old who doesn't particularly like arugula or radishes!
I loved this recipe! It was so simple to make and tasted so fresh. For step-by-step photos and more detailed commentary on this recipe, check out my post at: http://www.icancookthat.org/2013/03/radish-and-arugula-crostini-with-brie.html
