The other day I had to grab some fast food and got a "Classic Double w/cheese" from Wendy's - it turned out to be by far the best and easiest fast food burger I've dealt with since starting to lowcarb. It came with the cheese in between the two (large!) patties, so after I removed the bun, I could eat the hamburger like a sort of reverse-sandwich, with the meat in this case acting as the "bun". Tasty and convenient.
