I love me a messy sandwich. The more self-conscious I feel about having food all over my face, the more I think, "You know, I could use a bib right now," the more drippy goodness that's left on the plate, the more that's something that I'm going to enjoy. No doubt it's why one of my favorite places to eat ever is Primanti Brothers in Pittsburgh (Seriously, if you're ever in the area, go there. You will not be disappointed.).
I like messy sandwiches because most of the time it indicates that there are a lot of flavors on it. Lots of different veggies. Interesting sauces. Maybe some kind of fried goodness. It isn't usually pretty, but oh my. Bring on the flava-flav.
Anyway, while talking to Rich about how much I like messy burgers, I was careful to say that what makes a messy burger acceptable to me was that the bun holds up. We've probably all had a sandwich where the bread or roll holding it all together was far too flimsy for what it was trying to support. It just couldn't handle all that was being asked of it. So instead of just having stuff drip out of your sandwich, the whole thing just falls apart. That kind of messy is not so pleasant. A sloppy, soggy bun is not the most appetizing thing in the world. A solid, substantial bun can let a sandwich be messy while keeping it from turning disgusting.
