OK, so they're Morningstar Farms burgers. I love all their products, but this makes it somewhat less exciting to me since they are cheaper in the store and very easy to make (I usually throw a frozen patty on my Foreman Grill with some veggies like zucchini and onion). They are probably pretty tasty if BK flame-broils them like their regular burgers, too.
Still, it's nice to know that if I'm out and want to get something, BK has a great alternative to the same old Subway sandwich or grilled chicken. I'm so glad to see a restaurant adding something healty (sans mayo).
