Obviously you can use a meaty burger in place of the veggie burger if you like.
I used a SouthWest Sunshine Burger, one of my favorite non-meaty varieties.
This is more of a concept then a recipe, and that is:
Replace your burger bun with a piece of naan sliced in half
This particular burger is topped with lettuce, tomato, pepper-jack cheese, and delicious hummus.
It was delightful.
Go forth and naan-ify your buns!!!
