This recipe caught my eye on an episode of Barefoot Contessa because of the big chunks of cheese. I love any and all types of cheese, and the more flavor it can add to a salad, the better.
I wouldn't recommend assembling this too far in advance. If you are in a time crunch right before serving, you can cut the tomatoes and cheese, but keep them separate, and add the arugula right at the end. You may want to add a little more oil and vinegar than the recipe calls for in order to get a little more flavor.
