There's a restaurant in town that I eat at now and then. The food's decent and reasonably priced. As I ate my hamburger the other day I found myself wondering about an e-coli outbreak concerning romaine lettuce--the very type I was eating. The problem supposedly does not apply to Arizona, but I still found myself wondering about the lettuce on my sandwich. Frankly, I don't understand why they put romaine lettuce on sandwich's. It has that spine on it. It may be prettier than iceberg lettuce, but I'd rather have iceberg lettuce on my sandwiches. I just do not get it. Chefs out there what's the deal? Why use romaine lettuce on sandwiches instead of iceberg?
